  • OpenVPN/Tunnelblick through wireless router, no connection.

    - by Oscar
    I'm using OpenVPN with Tunneblick on my Macbook Pro to access a server on my job. I't works fine, but i can't get it working with my Netgear WGT624v3 wireless router. I get this warning: WARNING: potential route subnet conflict between local LAN [192.168.1.0/255.255.255.0] and remote VPN [192.168.1.0/255.255.255.0] Someone told me that i should "port forward" on my router, but i can't figure out the right settings. Also not shure i'm doing it right.

  • Multicasting and multicast address

    - by Zia ur Rahman
    I have confusion about the multicast addresses, I have read an example which is given by. Suppose two applications have been built to send audio over a network. One application accepts and digitizes an audio input stream, and then sends the resulting frame across the network to other application. The second application receives the digitized audio from the network, converts it back to the audio signal and plays the result over a speaker. Unless the two applications use broadcast to send frames, no other computers on the network will receive a copy of the frame. Multicasting provides an excellent solution to the problems of allowing some computers to participate in audio transmission. To use multicasting , a multicast address must be chosen for the audio application. And the receiving application passes the multicast address to the network interface. The interface begins to accept the packets sent to that address. Question: how this multicast address is chosen, how the receiving application knows that the sender using this specific destination address for the audio frames.

  • Building a Mac/PC Network in a Dorm with Network Restrictions

    - by user70340
    I have been a Windows XP user for the last few years, but I recently bought a 15'' MacBook Pro for research purposes. I would like to set up a no-hassle Mac/PC Network at home so that I can access the internet on both computers and hardware between computers (i.e. a harddrive, or a mouse/keyboard with Synergy). Unfortunately, I live in a dorm with silly network restrictions so a solution is not straightforward. In particular: The dorm has a wired and wireless network, both which provide an internet connection. The wired network provides way faster internet (download speeds of 15 MB/s vs. 2 MB/s on wireless), so I would like to somehow exploit this, at least on my PC for Bittorrent :) Multiple devices can connect to the wireless network, but cannot "see" each other on the network (so software like Synergy would not work). Only 1 MAC address can connect to the wired network at a time. Ideally I would just connect a wireless router to the wired network and then have both the Mac and the PC on that, but the 1 MAC address restriction will not allow the both computer to access the internet simultaneously. I cannot think of a way to bypass this restriction (though I'm not network savvy), so I am planning to create a private no-internet network to allow the devices to see each other and share hardware. Here are some thoughts. I would appreciate any feedback at all! If I build a private wireless network: (first choice) I will use a wireless router that is not connected to the internet. My PC and Mac will be connected to each other wirelessly. I can then connect the PC to the internet via a wired network, but then the Mac will not have internet access as its wireless card is already in use. In this case, could I stream internet access from the PC to the Mac via the wireless network? Or could I buy a USB wireless card for the Mac so that it can connect to both my private network and the dorm network? If I build a private wired network: (second choice) Then both the PC and the Mac will connect to the internet wirelessly, which means I cannot take advantage of the faster download speeds.

  • Can't ping through default gateway

    - by Andrew G.H.
    I have the following configuration: Routing table on M3 is: Destination Gateway Genmask Flags MSS Window irtt Iface 0.0.0.0 192.168.2.1 0.0.0.0 UG 0 0 0 eth1 192.168.2.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 192.168.3.0 0.0.0.0 255.255.255.192 U 0 0 0 eth0 Routing table on M1 is: Destination Gateway Genmask Flags MSS Window irtt Iface 0.0.0.0 192.168.0.1 0.0.0.0 UG 0 0 0 eth0 169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth1 192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 192.168.2.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 So basically M3's gateway is M1, and M1's gateway is M2's wireless internet interface. If I ping 8.8.8.8 from M1, everything is ok, replies are received. Pinging from M1 to M3 and viceversa is also possible. I have configured M1 as gateway trafic forwarder using firestarter package and stopped firewall with it. iptables policies are ACCEPT for everything. Problem: I have tried ping-ing ip 8.8.8.8 from M3 but without success. What could be the source of this problem?

  • Network use of Gaming PC

    - by Matthew Patrick Cashatt
    Background After YEARS of waiting, I built the custom gaming PC of my dreams: Intel i7 - 975 Extreme Edition 3.3ghz (overclocked to 4.0) ATI Radeon 5970 2gb Corsair 256 gb SSD Drive 2 TB Sata II 3.0 7200rpm data drive 12 GB Kingston Hyper-X (1600mhz) DDR3 Windows 7 Ultra 64 bit And so on. . . Problem I hooked this beast up to our home theater and settled in for a great gaming season only to realize a couple of drawbacks: It's hard to accurately wax bad guys using a keyboard in your lap whilst reclined on your couch (and using a wireless keyboard). It's hard to read the text on the screen (i.e. menus, etc). I find that a 1:1 ratio (screen diagonal inch to inch away from screen) is optimum, but using the home theater, it's more like 1:3 which has me squinting unless I sit on the coffee table. The wife always seems to want the TV the same time I do and, unfortunately "Real Housewives of Beverly Hills" and Battlefield BC don't mix. I am losing the battle in the home theater room, but the PC has to stay there (long story). So, this leaves me with the option of playing in my home office which is about 30 feet away from the home theater. I am a software developer so I have a pretty decent set up in my office--multiple 1080p monitors, HP Envy 17 which can run games like Crysis in 720p with out stammering too much. Also, I can game very comfortably at my desk in the office. Still, even though the set up in my office can run games well enough, I don't want to regress to that when I have worked YEARS for an awesome gaming PC that can run everything on ultra high settings. My Question What are my options for running my games on the beastly desktop in the Home Theater, but physically playing in my office about 30 feet away? A really long HDMI cable? LAN/RDC? Details that May Help We have an open crawlspace so running cable from HT room to office is no problem. I already have networked the house with a LAN Any help is GREATLY appreciated. Thanks, Matt

  • Windows Hosted Network Redirect to IIS

    - by rulestein
    I would like to setup a Windows 7 machine as a wifi hotspot that always redirects to the IIS web hosting on the same machine. I have the hotspot piece working with the built in hosted network of Widnows 7. The webhosting was easy enough with IIS. Now, how do I connect the 2? The idea is to have a standalone device that users will be able to connect to the wifi and any webpage they go to will redirect to the internal webpage. I only expect 1 or 2 users at a time and there won't be any internet access involved.

  • Static route works on one computer, not the other

    - by Dan
    I have been struggling with this for a couple days now, maybe I just need some people with a fresh perspective to figure out what the issue is. Basically I have a bunch of computers that are being routed through a specific gateway in order to access a web page that is hosted internally on a separate subnet. I set up static routes on all of the computers, and they all work... except one. Here's what a route print -4 looks like for a working computer (Windows 7): =========================================================================== Interface List 14...xx xx xx xx xx xx ......Broadcom 802.11n Network Adapter 11...xx xx xx xx xx xx ......Realtek PCIe GBE Family Controller 1...........................Software Loopback Interface 1 12...00 00 00 00 00 00 00 e0 Microsoft ISATAP Adapter 13...00 00 00 00 00 00 00 e0 Microsoft 6to4 Adapter 17...00 00 00 00 00 00 00 e0 Teredo Tunneling Pseudo-Interface =========================================================================== IPv4 Route Table =========================================================================== Active Routes: Network Destination Netmask Gateway Interface Metric 0.0.0.0 0.0.0.0 10.xxx.xxx.230 10.xxx.xxx.94 20 10.zzz.zzz.0 255.255.255.0 10.xxx.xxx.147 10.xxx.xxx.94 21 10.xxx.xxx.0 255.255.255.0 On-link 10.xxx.xxx.94 276 10.xxx.xxx.94 255.255.255.255 On-link 10.xxx.xxx.94 276 10.xxx.xxx.255 255.255.255.255 On-link 10.xxx.xxx.94 276 127.0.0.0 255.0.0.0 On-link 127.0.0.1 306 127.0.0.1 255.255.255.255 On-link 127.0.0.1 306 127.255.255.255 255.255.255.255 On-link 127.0.0.1 306 224.0.0.0 240.0.0.0 On-link 127.0.0.1 306 224.0.0.0 240.0.0.0 On-link 10.xxx.xxx.94 276 255.255.255.255 255.255.255.255 On-link 127.0.0.1 306 255.255.255.255 255.255.255.255 On-link 10.xxx.xxx.94 276 =========================================================================== Persistent Routes: Network Address Netmask Gateway Address Metric 10.zzz.zzz.0 255.255.255.0 10.xxx.xxx.147 1 =========================================================================== And here's a route print -4 from the station that doesn't work (also Windows 7): =========================================================================== Interface List 10...xx xx xx xx xx xx ......Realtek PCIe GBE Family Controller 1...........................Software Loopback Interface 1 12...00 00 00 00 00 00 00 e0 Microsoft 6to4 Adapter 14...00 00 00 00 00 00 00 e0 Microsoft ISATAP Adapter #2 16...00 00 00 00 00 00 00 e0 Teredo Tunneling Pseudo-Interface =========================================================================== IPv4 Route Table =========================================================================== Active Routes: Network Destination Netmask Gateway Interface Metric 0.0.0.0 0.0.0.0 10.xxx.xxx.230 10.xxx.xxx.132 276 10.zzz.zzz.0 255.255.255.0 10.xxx.xxx.147 10.xxx.xxx.132 21 10.xxx.xxx.0 255.255.255.0 On-link 10.xxx.xxx.132 276 10.xxx.xxx.132 255.255.255.255 On-link 10.xxx.xxx.132 276 10.xxx.xxx.255 255.255.255.255 On-link 10.xxx.xxx.132 276 127.0.0.0 255.0.0.0 On-link 127.0.0.1 306 127.0.0.1 255.255.255.255 On-link 127.0.0.1 306 127.255.255.255 255.255.255.255 On-link 127.0.0.1 306 224.0.0.0 240.0.0.0 On-link 127.0.0.1 306 224.0.0.0 240.0.0.0 On-link 10.xxx.xxx.132 276 255.255.255.255 255.255.255.255 On-link 127.0.0.1 306 255.255.255.255 255.255.255.255 On-link 10.xxx.xxx.132 276 =========================================================================== Persistent Routes: Network Address Netmask Gateway Address Metric 10.zzz.zzz.0 255.255.255.0 10.xxx.xxx.147 1 =========================================================================== Both of these stations are running Windows 7. So essentially what I am trying to do here is route all traffic to the 10.zzz.zzz.0 subnet through the 10.xxx.xxx.147 gateway. Everything else should go through the 10.xxx.xxx.230 gateway. This is the intended behavior, and again it is working everywhere but that one station. I noticed that the Active Route metric costs differ between the two stations, but I am new to the routing table and I am not sure how that is impacting the behavior. I hope I have been able to explain the situation clearly. Any help would be much appreciated. I can provide any additional information if needed!

  • Problems when trying to connect to a router wirelessly

    - by Ruud Lenders
    The situation - At my girlfriend's parents' place there are six Windows 7 devices that are wired or wireless connected to a router: 3 dekstops and 3 laptops. There are also several smartphones using the router. The router is secured with WPA2 (AES). The problem - We never had any problems with the router for over a year. But recently - about 3 weeks ago - my girlfriend's laptop (HP) and my laptop (ASUS) started to develop problems while trying to connect to the router. The router has stopped showing up from the network list. Sometimes it comes back and shows up, but then it keeps saying something along the lines of "Could not connect", and not long after that it dissapears again. The range of the router is not the problem here, because we experience the same when we sit next to the router. Sometimes, if we are lucky, and waited a long time (10-15 minutes) without using the laptop for anything, the laptop will eventually succesful connect to the router. The attempts - Of course, the Window 7 troubleshooter. We tried troubleshooting the connection problems and the wireless network adapter, but no luck. We also reset the router enough times to know that's not helping either. Here's the full list of things we tried, but did not help: Running the Windows 7 troubleshooter Resetting the router (more than once) Setting the router settings to factory defaults Disconnecting all other devices except one laptop Applying a system restore Trying static/dynamic IP/DNS - Dynamic is better, right? Enabling/disabling IPv6 - Should I keep IPv6 disabled? Running the command: netsh wlan stop hostednetwork Running the command: netsh wlan set hostednetwork mode=disallow Updating/reïnstalling wireless adapter drivers The tests - To help finding the core of the problem, we tested the following: Plugging an ethernet cable in the router and in our laptops - worked fine Connecting someone else's laptop to the router (wireless) - worked fine Connecting our laptops to someone else's router - worked fine The router - This information might be relevant: Router model: Sitecom 300N Wireless Router Router hardware: version 01 The DCHP Server's IPs range from 192.168.0.100 to 192.168.0.200. Router settings: Wireless channel: 12 Channel bandwidth: 20/40 MHz Extension channel: 8 Preamble type: Long 802.11g protection: Disabled UPnP: Enabled The laptops - If you are wondering about our laptops: My laptop model: ASUS Pro64JQ Girlfriend's laptop: HP Pavillion G6 OS: Both Windows 7 Professional x64 - with Service Pack 1 My wireless adapter: Atheros AR9285 AdHoc 11n: Enabled The question - Does anyone have experienced the same problems as I do? Or does someone know how to solve this? Are there more tricks I can try, or settings I should change? Note - Our laptops are not slow or old. My laptop is 1.5 years old, and the other laptop is just 5 months old. I know how to keep laptops clean and I'm pretty sure both laptops are not bloated with useless software.

  • OpenSuSE 11 iscsi target: HFS+ partition not seen by clients

    - by radiopaque
    I have an openSuSE machine as a file server, which has an Areca 1880i inside. It contains several partitions. There is a dm-0 and a dm-1 partition, for example. The partitions are formatted as EFI system partitions, with HFS+ file systems. My opensuse could not read them but the iscsitarget exported them for my Macs. This worked for more than a year. For some reason now, after some network problems which were "solved", my dm-0 partition is not seen anymore! I suspect it is a problem on the iscsi target side, i.e. the OpenSuSE machine. Can anyone suggest what I should look into? Any logs, any settings on the linux machine? None of my macs can access the partition, and they use different client software!! Thanks!

  • How to tell Windows 7 to ignore a default gateway

    - by zildjohn01
    I currently have 2 network cards in my PC -- one connected to an internal network on a router with a disconnected WAN port (10.x.x.x), and one connected to the internet through a consumer router (192.168.0.x). Windows seems to recognize them correctly (my "Network and Sharing Center" lists them as "No Internet" and "Internet" respectively), however when I try browsing the internet it always tries the internal network's default gateway, rather than the one with internet access. Trying to ping a website results in "Reply from 10.0.0.1: Destination net unreachable.". A simple "route delete 0.0.0.0 mask 0.0.0.0 10.0.0.1" fixes the problems, but they return upon reboot, or upon renewing my IP. Is there any way to tell Windows to ignore one NIC's default gateway, or to at least give them priorities?

  • Troubleshoot dropped wireless connections

    - by Jack
    I was recently hired in the IT department of a small company (~180 users) and one of the issues that people have been complaining about is having their wi-fi connections drop during meetings. The company is using an HP ProCurve Wireless LAN with 10 APs and a controller unit located in the server room. I don't have any experience troubleshooting WLAN in a multi-AP environment, so I'm trying to at least gather information using free or cheap tools. I did a basic site survey using the free version of Ekahau HeatMapper and discovered the following in one of the conference rooms that has been a problem. The program picked up three access points (plus a bunch of others with much lower signals that were out of range): AP 1: SSID: "Unknown SSID" - Signal strength: -48 dBm - -40 dBm. Channel: 2 AP 2: SSID "CompanyMain" - Signal strength: -35 dBm or greater. Channel: 2. Security: WEP (This is the main SSID for the company's WLAN.) AP 3: SSID: "CompanyGuest" - Signal strength: -40 dBm - -35 dBm. Channel: 2. Security: WPA2 (This SSID is the company's "guest" WLAN, which was setup to allow Internet access, but prevent network access.) Is there anything that you see that is clearly a problem from the above? I'm assuming that the unknown SSID might be a big problem, and that it is an AP from a neighboring office that is causing interference. Does that seem likely? Also, regarding channel, should we try changing the channels of our APs to avoid interference with that unknown SSID? (Since everything seems to be on Channel 2?) Should our APs be on different channels? In other words, should the CompanyMain and CompanyGuest APs be on different channels? Finally, any recommendations for free/cheap tools to help me figure this out, and/or a good methodology to follow? Thanks in advance for any help. Jack

  • how to run an AFS file server on a specific ethernet card (in Debian)

    - by listboss
    I have a linux box running Debian server with minimal number of packages (so no GUI for network management). The box has two ethernet cards, one of which (eth0) is connected to a Mac OSX computer using a cross-cable. I can bring up eth0 and assign a static ip (10.10.11.16) to it. This way I can ssh to the box through the cross-cable. This is what I run on Linux box: ifconfig eth0 10.10.11.16 netmask 255.255.255.0 up I also installed/started a file server (AFS) on Debian. So far, the file server can only be accessed through eth1 which is exposed to my home LAN and www. My goal is to set up the file server so that it's only visible through eth0. Is this possible? and if yes, how can I do it?

  • Windows redirect traffic to different DNS name not fixed IP address (hosts file equivalent)

    - by Arik Raffael Funke
    Using the Windows hosts file, one can redirect traffic for a domain to a specific IP address, e.g. domainA.com -- 127.0.0.1 I am looking for a SIMPLE way to do the same, but for a target domain name not for a target IP address (as this is dynamic), I.e. domainA.com -- domainB.com Addition: After the getting some initial answers I think I need to concretise my question. Situation: I have an application which looks up the IP of the target domain via DNS and then connects via HTTP to the IP address. I do not have control over any proxy settings. Option 1 Basically I am looking for a way to: intercept DNS requests for a domainA.com launch a DNS request for a domainB.com serve the IP of domainB.com in response to the request for domainA.com Without running an entire DNS server. Option 2 If a DNS server is the only way, in the alternative I would also be happy with an solution to how to define a non-standard DNS-server for a single application. Any ideas for wrapper applications, etc?

  • Make case-sensitive SMB share case-insensitive

    - by fungs
    I am running a legacy XP app that I would like to move on a network share. It is very simple and works in theory but the server providing the share is based on Linux (cannot configure) and the software does not work correctly because it is programmed case-insensitively, it seems. After some research, network shares behave like the filesystem they use underneath. This is normal. Unfortunately I cannot fix the software myself. Is there any way to turn the case-sensitivity into case-insensitivity for a Windows network drive on the client side? I fould two approaches: First, something like icasefile (http://wnd.katei.fi/icasefile/) that wraps around the program and intercepts the file I/O. This is for UNIX only. Secondly, a proxy virtual file system (e. g. something using Dokan). Unfortunately I couldn't find any suitable fs, the only possibility would be to put a case-insensitive filesystem on an image file and put this on the share using for example lmdisk (http://www.ltr-data.se/opencode.html/#ImDisk). Do you have any better ideas?

  • Transparent proxy which preserves client mac address

    - by A G
    I have a customer that wants to intercept SSL traffic as it leaves their network. My proposed solution is to setup a proxy that is transparent and both layer 2 and layer 3 so it can simply be dropped into their network without any change in config required. The proxy has two NICs, one connected to the server, the other to the client. The client, proxy and gateway are under control of the customer, the server is not. For example: client --- Proxy --- gateway -|- server I have my proxy program configured with IP_TRANSPARENT socket option to it can respond to connections destined for a remote IP. I am using the following setup: iptables -t mangle -A PREROUTING -p tcp --dport 80 -j TPROXY --on-port 3128 --tproxy-mark 1/1 iptables -t mangle -A PREROUTING -p tcp -j MARK --set-mark 1 ip rule add fwmark 1/1 table 1 ip route add local 0.0.0.0/0 dev lo table 1 The client in question is on its own subnet and has been configured so that the proxy is the default gateway. The result is: Client sends a frame to the proxy; source IP is client, source mac is client, destination IP is server, destination mac is proxy Proxy forwards this frame to the gateway; source IP is proxy, source mac is proxy, destination IP is server, destination mac is gateway Gateway forwards this to the server and gets a response back. Gateway sends reply back to proxy; source IP is server, source mac is gateway, destination IP is proxy, destination mac is proxy Proxy forwards this reply to client; source IP is server, source mac is proxy, destination IP is client, destination mac is client. The tproxy and iptables configuration lets the proxy send packets with a non local ip address. Is there a way to make something transparent at the mac address level? That is, put the client on the same subnet as the gateway. The gateway sees the source IP and mac as that of the client, even though they originated from the proxy. Could this be done by configuring the proxy as a bridge then use ebtables to escalate the traffic to be handled by iptables? When I use ebtables to push something up to iptables, it appears my proxy program doesn't respond to the packets as they are destined for the gateways's mac address, not the proxy's. What are some other potential avenues I could investigate? EDIT: When the client and gateway are on different subnets (and client has set the proxy as the gateway), it works as described in 1 to 5. But I want to know if it is possible to have the client and gateway on the same subnet and have the proxy fully transparent (ie client is not aware of the proxy). Thanks! EDIT 2: I can configure the proxy as a bridge using brctl, but cannot find a way to direct this traffic to my proxy program - asked here Possible for linux bridge to intercept traffic?. Currently, with the description numbered 1 to 5, it operates at layer 3; it is transparent on the client side (client thinks it is talking to the server's IP), but not on the gateway side (gateway is talking to the proxy's IP). What I want to find out is, is it possible to make this operate at layer 2, so it is fully transparent? What are the available options I should research? Thanks

  • network topology including many services

    - by mete
    I know this is yet another question on how to setup network but I hope you are not bored of such questions yet. The site is also an office, so it includes windows dc, windows ad, exchange, sql, file sharing, development app servers and other pcs. In addition to office (internal) things, there are both test and prod environments consisting of a web server-app server-sql stack. There is also ftp service open to public. I consider: dmz1 - web server - exchange edge - ftp dmz2 - app server - sql for app server internal - dc and ad - exchange hub and transport - internal file sharing - sql for internal use - app servers for internal use - pcs public - dmz1, only web, ftp and smtp public - dmz2 not possible public - internal not possible dmz1 - dmz2 is possible from web servers to app servers by using http or ajp dmz1 - internal is only possible for exchange, otherwise not possible dmz2 - internal not possible Does this sound ok ? Any other recommendations ? It will be configured using either MS ISA or Jupiter SSG. Thank you.

  • Connecting 2 different subnet masks

    - by Jonathan
    I'm no network genius, but I have managed to get most things running. I get confused about subnets and gateways though. We have an office server connected to around 20 PC's that all communicate fine. We have just gotten a cutting machine that won't connect to our network. The server has DHCP, but that fails on the cutting machine, so I've been trying to set the IP manually. Server details are as follows: IP: 10.1.1.12 SUBNET: 255.255.255.0 GATEWAY: 10.1.1.1 Internet connection is via the modem which is 10.1.1.1 An office PC is ussually set up through DHCP and has the following settings: IP: 10.1.1.36 SUBNET: 255.255.255.0 GATEWAY: 10.1.1.1 PRIMARY DNS: 10.1.1.12 Cutting Machine computer has 2 network ports. 1 is specifically for the communication between the PC and the cutting machine. It's details must be as follows: IP: 10.100.100.2 SUBNET: 255.255.255.252 GATEWAY: BLANK The other network port need to connect to the server. I was told that the IP and SUBNET need to be as follows: IP: 10.100.100.1 SUBNET: 255.255.255.252 GATEWAY: ?? How can I connect this port to the server and/or the internet. If anyone can offer assistance, it would really be appreaciated.

  • Incorrect Windows 7 "No Internet Access" notice

    - by Joel Coehoorn
    In windows 7, I have a wifi network that shows up with a warning icon overlay and the "No internet access" description as shown in this image: The other network shown there is a VirtualBox VM, and is expected to show that way. Plainly, this notice is wrong as I have been browsing with that connection all afternoon and used it to post this question. So my question is, what makes this message come up, and how can I make it go away?

  • Windows 7 VPN Error 619

    - by TravisPUK
    So I am running Windows 7 Enterprise. This morning I was able to VPN using the built in VPN (Connect to Work Network etc). I had to change my network's IP address range and now the VPN will not work. It just stalls on the Verifying user name and password... message. But then it returns the 619 error. Anybody know why changing my machine's IP address would cause this problem? Where should I be looking to try and fix this issue? I have tried this on a Windows XP machine that also had the IP address range change and this still connects fine using exactly the same connection details. EDIT The internal network range changed from 192.x.x.x to 10.x.x.x. This was done on the entire Active Directory. All machines are running fine and the Windows XP machine, that works going to the same client VPN mentioned above is on the same network. Both the XP and the Win 7 machines are using DHCP served by the Domain Controller. The client domain is not performing any IP range checks/restrictions. The VPN is outside the internal network, connection is being made via the Internet and not passing through any other machine, other than the normal domain machines, ie DNS etc. This is passing through a router and the router has the relevant VPN passthrough options configured. All internal machines are working correctly with other forms of VPN, ie Cisco, Sonic etc (these were tested on other machines, they are not installed on the Vista or Win7 machines). After further testing, this is occurring on all Win7 and Vista machines where they can no longer connect to the client VPN, however all XP machines can still connect fine. This has been tested on three Vista, two Win7 and five XP machines. All machines are on DHCP and tests have been done with both the firewalls turned on and off, as well as with fixed IPs being used. Thanks Travis
