• How to use CLEAR USB internet connection in Ubuntu (host) and WindowsXP (guest) using VirtualBox

  - by bithacker

  I'm trying to use CLEAR Motorola WiMax USB in Ubuntu as there is no support for linux as yet. I've installed windowsxp as guest in ubuntu and the version I'm using is 3.2.2. USB is connecting fine in WindowsXP but I can't use internet in Ubuntu. Can you please tell me how to do it. Here is the configuration that could help you guys. Thanks in advance. I'm using Two Network Adapters.

• GNS3 Cannot ping/resolve DNS record

  - by Eldad Cohen

  I set up an internet lab with GNS3, which has 3 routers, in each node there is a computer directly connected. One of the hosts is a DNS server, Windows 2003 Server. The other one is a Windows XP machine. Ping is good between routers and machines but no ability to ping domain.com record on DNS server 2003. I set a static nat on the router to route all traffic from gateway to the DNS server internal ip address, still no answer for the dns request. Any ideas or thoughts will be most welcome.

• is there any Open Soruce solution for Failover of incoming Traffic?

  - by sahil

  Hi, We have two ISP... and both ISP's Ip Nat with same Webserver IP, i want failover for incoming traffic , is there any open source solution? can i do it by making two name server , one for each ISP? ... I am not sure but as per my knowledge primary and secondary name server will reply in round robin method till they are live , once any name server will be unreachable then only another will be reply...so if i am right then i think i can do incoming failover by making two name server in my office... Waiting for your valuable response... Thanking you, Sahil

• Get source and destination of outbound traffic in pfSense

  - by maxsilver

  I'm looking at the traffic graph in pfSense (Version 1.2.2), which we're using as a router / NAT / ect on our network. Recently, I'm seeing a sudden, constant spike of 15 - 30kbps traffic outbound, that is unusual for our network (normally its below 2kbps, we're mostly all inbound traffic) Is there any way to determine what the source of this traffic is, or where it's going? (Just an internal IP address for source, and external IP address for destination would be all I need) I've already tried switching the traffic graph to 'LAN' and watching the host list on the right side, but it seems ... flakey. The numbers it shows seem to fade in and out at random, and the values never add up to anywhere near the graph values. I'm not allowed to post the image, but a photo is available at - http://imgur.com/QYjKI.png

• CheckPoint VPN-1 SecureClient inability to navigate behind a Linksys WAG300N

  - by user46819

  I have a Linksys WAG300N, I'm accessing my LAN with Wifi and everything works fine on my Windows 7 Enterprise laptop. When I try to connect to my company's VPN the connection succeeds, but I cannot access any internet site either within my work network or public site like Yahoo or Google. In my Linksys control panel I already verified all types of VPNs are enable to passthrough. Normal IPSec and Windows VPN worked in the past without any problems. CheckPoint seems to have a solution, but I do not have the ability to change the IP in my client and of course using another NAT device in between is not a solution for me. Edit: adding link to the Checkpoint solution, https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doGoviewsolutiondetails=&solutionid=sk26189

• Configure Windows Routes for VPN

  - by Florin Sabau

  I have a Virtual PC/VMWare machine that runs Windows Server 2003. This virtual machine uses an IPSec VPN client program to connect to a remote network. I configured the virtual machine to have 2 NICs: NAT - to be used by the VPN Client to access the remote network Host only - to be able to access the virtual machine from the host The reason I have this setup is because I want to be able to access some remote network from the host machine. I could've installed the VPN client on the host machine, but the host runs Windows 7 and the client doesn't support it. The problem: although the virtual machine is normally reachable (ping + http access), as soon as the VPN client is started, neither of the NIC addresses are reachable anymore. I'm wondering if it is a routing problem that needs to be addressed? How do routing/VPN client connection affect the ability of the server to respond to client requests from the host?

• Can't access shared drive when connecting over VPN

  - by evolvd

  I can ping all network devices but it doesn't seem that DNS is resolving their hostnames. ipconfig/ all is showing that I am pointing to the correct dns server. I can "ping "dnsname"" and it will resolve but it wont resolve any other names. Split tunnel is set up so outside DNS is resolving fine So one issue might be DNS but I have the IP address of the server share so I figure I could just get to it that way. example: \10.0.0.1\ well I can't get to it that way either and I get "the specified network name is no longer available" I can ping it but I can't open the share. Below is the ASA config : ASA Version 8.2(1) ! hostname KG-ASA domain-name example.com names ! interface Vlan1 nameif inside security-level 100 ip address 10.0.0.253 255.255.255.0 ! interface Vlan2 nameif outside security-level 0 ip address dhcp setroute ! interface Ethernet0/0 switchport access vlan 2 ! interface Ethernet0/1 ! interface Ethernet0/2 ! interface Ethernet0/3 ! interface Ethernet0/4 ! interface Ethernet0/5 ! interface Ethernet0/6 ! interface Ethernet0/7 ! ftp mode passive clock timezone EST -5 clock summer-time EDT recurring dns domain-lookup outside dns server-group DefaultDNS name-server 10.0.0.101 domain-name blah.com access-list OUTSIDE_IN extended permit tcp any host 10.0.0.253 eq 10000 access-list OUTSIDE_IN extended permit tcp any host 10.0.0.253 eq 8333 access-list OUTSIDE_IN extended permit tcp any host 10.0.0.253 eq 902 access-list SPLIT-TUNNEL-VPN standard permit 10.0.0.0 255.0.0.0 access-list NONAT extended permit ip 10.0.0.0 255.255.255.0 10.0.1.0 255.255.255.0 pager lines 24 logging asdm informational mtu inside 1500 mtu outside 1500 ip local pool IPSECVPN-POOL 10.0.1.2-10.0.1.50 mask 255.255.255.0 icmp unreachable rate-limit 1 burst-size 1 asdm image disk0:/asdm-621.bin no asdm history enable arp timeout 14400 global (outside) 1 interface nat (inside) 0 access-list NONAT nat (inside) 1 0.0.0.0 0.0.0.0 static (inside,outside) tcp interface 10000 10.0.0.101 10000 netmask 255.255.255.255 static (inside,outside) tcp interface 8333 10.0.0.101 8333 netmask 255.255.255.255 static (inside,outside) tcp interface 902 10.0.0.101 902 netmask 255.255.255.255 timeout xlate 3:00:00 timeout conn 1:00:00 half-closed 0:10:00 udp 0:02:00 icmp 0:00:02 timeout sunrpc 0:10:00 h323 0:05:00 h225 1:00:00 mgcp 0:05:00 mgcp-pat 0:05:00 timeout sip 0:30:00 sip_media 0:02:00 sip-invite 0:03:00 sip-disconnect 0:02:00 timeout sip-provisional-media 0:02:00 uauth 0:05:00 absolute timeout tcp-proxy-reassembly 0:01:00 dynamic-access-policy-record DfltAccessPolicy aaa authentication enable console LOCAL aaa authentication http console LOCAL aaa authentication serial console LOCAL aaa authentication ssh console LOCAL aaa authentication telnet console LOCAL http server enable http 10.0.0.0 255.255.0.0 inside http 0.0.0.0 0.0.0.0 outside no snmp-server location no snmp-server contact snmp-server enable traps snmp authentication linkup linkdown coldstart crypto ipsec transform-set myset esp-aes esp-sha-hmac crypto ipsec transform-set ESP-3DES-SHA esp-3des esp-sha-hmac crypto ipsec security-association lifetime seconds 28800 crypto ipsec security-association lifetime kilobytes 4608000 crypto dynamic-map dynmap 1 set transform-set myset crypto dynamic-map dynmap 1 set reverse-route crypto map IPSEC-MAP 65535 ipsec-isakmp dynamic dynmap crypto map IPSEC-MAP interface outside crypto isakmp enable outside crypto isakmp policy 10 authentication pre-share encryption 3des hash sha group 2 lifetime 86400 crypto isakmp policy 65535 authentication pre-share encryption aes hash sha group 2 lifetime 86400 telnet 0.0.0.0 0.0.0.0 inside telnet timeout 5 ssh 0.0.0.0 0.0.0.0 inside ssh 70.60.228.0 255.255.255.0 outside ssh 74.102.150.0 255.255.254.0 outside ssh 74.122.164.0 255.255.252.0 outside ssh timeout 5 console timeout 0 dhcpd dns 10.0.0.101 dhcpd lease 7200 dhcpd domain blah.com ! dhcpd address 10.0.0.110-10.0.0.170 inside dhcpd enable inside ! threat-detection basic-threat threat-detection statistics access-list no threat-detection statistics tcp-intercept ntp server 63.111.165.21 webvpn enable outside svc image disk0:/anyconnect-win-2.4.1012-k9.pkg 1 svc enable group-policy EASYVPN internal group-policy EASYVPN attributes dns-server value 10.0.0.101 vpn-tunnel-protocol IPSec l2tp-ipsec svc webvpn split-tunnel-policy tunnelspecified split-tunnel-network-list value SPLIT-TUNNEL-VPN ! tunnel-group client type remote-access tunnel-group client general-attributes address-pool (inside) IPSECVPN-POOL address-pool IPSECVPN-POOL default-group-policy EASYVPN dhcp-server 10.0.0.253 tunnel-group client ipsec-attributes pre-shared-key * tunnel-group CLIENTVPN type ipsec-l2l tunnel-group CLIENTVPN ipsec-attributes pre-shared-key * ! class-map inspection_default match default-inspection-traffic ! ! policy-map global_policy class inspection_default inspect icmp ! service-policy global_policy global prompt hostname context I'm not sure where I should go next with troubleshooting nslookup result: Default Server: blahname.blah.lan Address: 10.0.0.101

• virtualbox ftp hangs on list command

  - by Tiddo

  Hi all, I have virtual box installed on a windows 7 64-bit computer, with Cent OS 5.5 as guest os. I want to be able to use ftp between those. I've installed vsftpd on the guest os, and the guest os uses a nat connection with the host os for internet. So far, I am able to connect to the guest os using ftp (in filezilla), but after the list command is executed, nothing happens, until the command is timed out. This happens in both active and passive mode. I do have set a pasv_min/max_port in the vsftpd.conf file, listing is enabled, and the ports are redirected in virtualbox. Also the ftp_data_port is set to 20. I also tried setting the pasv_address, but I had to set it to 127.0.0.1, but than filezilla gives me this: Command: PASV Response: 500 OOPS: bad family Command: PORT 127,0,0,1,139,204 Response: 500 OOPS: child died Can someone help me with this?

• Iptables based router inside KVM virtual machine

  - by Anton

  I have KVM virtual machine (CentOS 6.2 x64), it has 2 NIC: eth0 - real external IP 1.2.3.4 (simplified example instead of real one) eth1 - local internal IP 172.16.0.1 Now I'm trying to make port mapping 1.2.3.4:80 = 172.16.0.2:80 Current iptables rules: # Generated by iptables-save v1.4.7 on Fri Jun 29 17:53:36 2012 *nat :OUTPUT ACCEPT [0:0] :PREROUTING ACCEPT [0:0] :POSTROUTING ACCEPT [0:0] -A POSTROUTING -o eth0 -j MASQUERADE -A PREROUTING -p tcp -m tcp -d 1.2.3.4 --dport 80 -j DNAT --to-destination 172.16.0.2:80 COMMIT # Completed on Fri Jun 29 17:53:36 2012 # Generated by iptables-save v1.4.7 on Fri Jun 29 17:53:36 2012 *mangle :PREROUTING ACCEPT [0:0] :INPUT ACCEPT [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [0:0] :POSTROUTING ACCEPT [0:0] COMMIT # Completed on Fri Jun 29 17:53:36 2012 # Generated by iptables-save v1.4.7 on Fri Jun 29 17:53:36 2012 *filter :INPUT ACCEPT [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [0:0] COMMIT # Completed on Fri Jun 29 17:53:36 2012 But there is nothing works, I mean it does not forwards that port. Similar configuration without virtualization seems to be working. What am I missing? Thanks!

• On RouterOS, how will transparent proxying (with DNAT) affect reporting of netflows?

  - by Tim

  I have a box running Mikrotik RouterOS, which is set up to do transparent web proxying, as described here. In short, this means that I have a firewall rule for destination NAT causing any port 80 traffic to get redirected to port 8080 on the router, which is received by the Mikrotik local web proxy. The local web proxy then makes the web request on the client's behalf, in this case to a parent web proxy server (which in turn does the real web request). My question is, how will this two-part process get reported in the logging of traffic flow information (netflows)? Looking at the logged information, what I seem to be seeing is this: One flow recorded from client machine (private IP) to remote proxy (8080) Another flow recorded from router to remote proxy (8080) The original request that the client made to port 80 isn't recorded. I want to write code to analyse traffic usage, so I want to be sure I'm not losing information if I discard the latter of these.

• multiple vlans routed on one nic? trunk?General? or Access?

  - by Aceth

  ok for the last week I've tried racking my head around this... I have a SRW208P with 802.1q support, and a virtual endian appliance. I would like to be able to have 3 vlans having everything routed through the endian appliance.. i.e. The Virtual server has 2 bridged NIC's to the switch. This is where I'm getting confused .. On the 8 port switch I've got the 3 vlans set up ok (all being untagged as they are not going to be vlan aware), it's the port I'm connecting the endian firewall to the switch I'm having trouble with (second nic goes to the adsl modem and NAT'd) Is it meant to be a trunk, "Genereal" or "Access" then untagged or tagged? the end goal is to have vlan traffic routing through the single NIC and have endian route vlan traffic according to the rules. Any one have any ideas on the cisco small business stuff? Thanks

• Should I Upgrade My Old Wireless Router?

  - by lyngbym

  I have an old wireless router, and I mean stone age old (5 years). There is nothing wrong technically with the router, it serves my wireless needs at home but it is really darn old. A search on Belkin's site for F5D7230-4 actually turns up a different old model so I scrounged up this old review for you to get a sense of what I'm running: http://www.pcmag.com/article2/0,2817,1572451,00.asp. Is there a valid security reason to replace this router in 2009? Google searches have turned up a few security threats to it and Belkin hasn't released new firmeware in years for it. I am starting to think I should replace it mainly because its NAT is about the only thing protecting me from the outside world. Buying a new wireless router is a boring way to spend money since it just sits on a shelf doing its job. Thoughts?

• IPv6 6to4 on Windows Server

  - by Graham Wager

  I'm looking for a relatively simple guide to setting up IPv6 properly on a home network. This network currently has a server (Windows Server 2008R2) running RRAS that establishes connectivity to the internet using a demand-dial PPPoE connection and handles the NAT. It also hosts a DNS server and DHCP. My ISP does not support IPv6, but I have a static IPv4 address. I've read about 6to4 and signed up at tunnelbroker.net, but quickly felt out of my depth. How do I configure my network to use it, and how I should configure my DHCP server with regards to IPv6 addresses?

• Linksys EA3500 : use WAN port as WAN + LAN possible?

  - by Dough

  I'm waiting for deliver of a Linksys EA3500 router. I was wondering if it was possible to get the WAN port act as normal WAN port (Internet IP) + LAN switch ? My problem is that my Internet box is in a room with NAS and PC, and the router will be in another room with TV, PS3 and PC. The Internet box have a 4 port Gigabit switch so one cable will plug from there to the router's WAN in the other room. The router will get the Internet IP from the Internet box, but will it be possible to have private network through this link too ? I could have a first network between the Internet box and the router, and another network form router and devices but that will do double NAT for nothing... Thanks for reading me and your help !

• Port forwarding through a client bridge

  - by Gabe Tanenhaus

  I am having a problem with port forwarding with a client bridge. My main router is a 2wire router from AT&T using their firmware. It is a Router/Modem. In my room, there is a Linksys WRT54GL with DD-WRT on it. I have set up the DD-WRT one as a Client bridge for my PC. I can access the internet on my computer using it but when I try and port forward, the ports stay closed. I am port forwarding on my main router (2wire) and it doesn't work. I have checked online and all I see is that I should only need to forward on the main router since the client bridge has NAT disabled, but it seems to not work that way. Any ideas?

• Route an IP from WAN to a host on LAN on OpenWRT

  - by Zsub

  EDIT: I know how to use NAT, I specifically want the server to be reachable on two IP's, one private, one public, with the firewall of the OpenWRT in between, if feasible. At the office we have recieved a /29 from our ISP. The first address is reserved for their endpoint, so I'm free to use five addresses. We run a local network, so of course there is a router in between running OpenWRT to provide all hosts with (W)LAN (dhcp from a private range). However, we also have a server running OS X Server 10.6 (Snow Leopard) and I'd like that server to be accessible both from the LAN using a private IP as well as from the WAN on it's own public IP. Point of note is that the server only has one network port, so multiple NICs is not an option, unfortunately. How would I go about doing this?

• How does IPv4 Subnetting Work?

  - by Kyle Brandt

  This is a Canonical Question about IPv4 Subnets How does Subnetting Work, and How do you do it by hand or in your head? Can someone explain both conceptually and with several examples? Server Fault gets lots of subnetting homework questions, so we could use an answer to point them to on Server Fault itself. What is classless routing and why is class-based routing obsolete? If I have a network, how do I figure out how to split it up? If I am given a netmask, how do I know what the network Range is for it? Sometimes there is a slash followed by a number, what is that number? Sometimes there is a subnet mask, but also a wildcard mask, they seem like the same thing but they are different? Someone mentioned something about knowing binary for this? What is NAT (Network Address Translation).

• Send notification from HTTP bot (RESTful service or whatever)

  - by Kuroki Kaze

  I have very simple bot that gathers and parses web pages. It's on a machine in network, behind NAT (so I cannot setup a web server, for example). I don't have MTA set up. The bot should notify me about changes in parsed pages (once in a hour or two, to one recipient). How can this be done? Is there any RESTful email gateways, like SMS ones? I can set up him a twitter account and use curl to post statuses/DM, but it's a very temporary bot.

• Waht are the best proxy servers for Mikrotik router?

  - by niren

  I want to setup proxy server for my Mikrotik router. There is inbuilt web-proxy for Mikrotik router but I can extend this upto transparent proxy(kind of proxy server) only. We need High anonymity proxy so that we can hide our LAN static IPs(we don't have private IP) from outside Intruder/hackers. And also I know I can setup NAT rule to hide our IP(only private IP not public/static IP) as per this link, but I cann't hide static/public IP. Essentially I want to hide our Public/Static IP (there is static/public IP for all systems in our company) from outside Internet. To achieve this I guess I need other software apart from Mikrotik router gateway setup. can anyone suggest me Is there any other software to achieve my requirement? I know about squid proxy but am not sure whether It can hide our static/public IP. Note: we have assigned public/Static IP to all systems of our company since we have rights to access our company's system from anywhere by dedicated laptop(given by our company with more security) through VPN connection.

• Connect to MySQL EC2 Instance outside of VPC

  - by Brian W

  I have a VPC setup with a few EC2 instances inside. I'm attempting to connect to a MySQL database on an EC2 instance outside the VPC, with no luck. I have the security groups on the VPC EC2 instances set to outbound 0.0.0.0/0 which I assumed would let it connect to any outbound connection. I also followed a tutorial on creating a NAT, but wasn't exactly sure how to use it to connect to an external database. In any case, if anyone has experience and knows the proper way to connect to a database outside the VPC, it would be greatly appreciated!
