  • Using ClearOS as a gateway/firewall/mailserver

    - by Elzenissimo
    Hi, Just installed ClearOS on a PC to act as our firewall firstly and then to act as an internal mailserver. My question is: Can i create a mailserver that then routes the mail through to our ISP mail server without having to contact the ISP and gain MX records etc..? We are a small business (5 PCs + dataserver) and the reason this is interesting is because we need to keep a record of outgoing mails from certain users, as well as spam and virus filtering.

  • Using Android 2.0 with Exchange server behind firewall

    - by Yurik
    Blackberry has an enterprise server that works with MS Exchange, and pushes all updates to the user's blackberry devices. We are considering switching to Android phones, which supposedly support Exchange servers. Will there be a similar program for Android? Are there any configuration changes that have to be done on Exchange server? (Exchange is behind the corp firewall).

  • Remember Snow Leopard Firewall settings

    - by revelator
    I've got the firewall enabled on my Snow Leopard installation, and it works just fine, except for with EyeTV. Every time I run this app, a popup appears asking if I want to allow it access to the network, even though I've got it added in the application list for allowed apps. Any ideas how I can stop this from asking and just let it be given access?

  • Convert IP Address format from ForeFront Firewall logs with SQL

    - by TrevJen
    I am trying to query IP addresses from Forefront Firewall logs, and I am a little stuck on the IP formatting C0A8E008-FFFF-0000-0000-000000000000 Can anyone give me the MSSQL command to turn this into standard human redable? UPDATE, I now see that I kust need to convert the first 8 charecters from hex to decimal....which I can then convert to IP. the trick is to parse those first charecters from the field with SQL

    Hi, my OS is Windows Server 2003. I installed the FTP Service and configure it with the IIS 6.0 Console. When I deactivate my firewall, all its okay, but when not, I can't get a connection. Port 21 tcp + udp, port 22 tcp + udp and the whole FTP-Server Application is set as go trouhgt, but don't work. Of course, the FTP ruins on 21. Any ideas

  • Secure Standalone Server Plus Firewall Unit [closed]

    - by orbitron
    We need to send a 2U server, 1U UPS and 1U firewall to a third-party. The thing is, it needs to be a secured case (locked unit) that has proper airflow and we can have power and networking cables coming out of the back. We've googled far and wide and have only been able to find 'hard case' units that offer some level of security but they are extremely bulky and require freight delivery. Thank you for any insight or solutions.

  • PPTP connection fails with errors 800/806

    - by Mark S. Rasmussen
    I've got a client (Server 2008 R2) that won't connect to our production environment PPTP VPN server (Server 2003, running RRAS). The server is behind a firewall that has TCP1723 open as well as GRE. Other clients at our office are able to connect just fine. Our office is behind a Juniper SSG5-Serial firewall, but all outgoing traffic is allowed, and multiple other clients are able to connect to VPN servers without issues. I've also setup a completely different VPN server on another network outside of our office. The functioning clients connect just fine - the Server 2008 R2 machine doesn't. Thus it's definitely a problem with this machine in particular. I've rebooted it. I've disabled the firewall, no dice on either. I've run PPTPSRV and PPTPCLNT on the server/client and they're able to communicate perfectly - indicating there's no problem using neither TCP1723 nor GRE. The Server 2008 R2 machine is also running as a VPN server itself (incoming connection) and that's working perfectly. We have the issues no matter if there are active incoming connections or not. I'm not sure what my next debugging step would be; any suggestions? EDIT: The event log on the server has the following warning from RasMan: A connection between the VPN server and the VPN client xxx.xxx.xxx.xxx has been established, but the VPN connection cannot be completed. The most common cause for this is that a firewall or router between the VPN server and the VPN client is not configured to allow Generic Routing Encapsulation (GRE) packets (protocol 47). Verify that the firewalls and routers between your VPN server and the Internet allow GRE packets. Make sure the firewalls and routers on the user's network are also configured to allow GRE packets. If the problem persists, have the user contact the Internet service provider (ISP) to determine whether the ISP might be blocking GRE packets. Obviously this points to GRE being a potential problem. But seeing as I have other clients connectiong without problems, as well as PPTPSRV and PPTPCLNT being able to communicate, I'm suspecting this might be a red herring. EDIT: Here are the anonymized events logged by the client in chronological order: CoId={742CB15C-A7E0-47B7-8240-0EFA1139CBD9}: The user XXX\YYY has started dialing a VPN connection using a per-user connection profile named ZZZ. The connection settings are: Dial-in User = XXX\YYY VpnStrategy = PPTP DataEncryption = Require PrerequisiteEntry = AutoLogon = No UseRasCredentials = Yes Authentication Type = CHAP/MS-CHAPv2 Ipv4DefaultGateway = No Ipv4AddressAssignment = By Server Ipv4DNSServerAssignment = By Server Ipv6DefaultGateway = Yes Ipv6AddressAssignment = By Server Ipv6DNSServerAssignment = By Server IpDnsFlags = Register primary domain suffix IpNBTEnabled = Yes UseFlags = Private Connection ConnectOnWinlogon = No. CoId={742CB15C-A7E0-47B7-8240-0EFA1139CBD9}: The user XXX\YYY is trying to establish a link to the Remote Access Server for the connection named ZZZ using the following device: Server address/Phone Number = XXX.YYY.ZZZ.KKK Device = WAN Miniport (PPTP) Port = VPN3-4 MediaType = VPN. CoId={742CB15C-A7E0-47B7-8240-0EFA1139CBD9}: The user XXX\YYY has successfully established a link to the Remote Access Server using the following device: Server address/Phone Number = XXX.YYY.ZZZ.KKK Device = WAN Miniport (PPTP) Port = VPN3-4 MediaType = VPN. CoId={742CB15C-A7E0-47B7-8240-0EFA1139CBD9}: The link to the Remote Access Server has been established by user XXX\YYY. CoId={742CB15C-A7E0-47B7-8240-0EFA1139CBD9}: The user XXX\YYY dialed a connection named ZZZ which has failed. The error code returned on failure is 806. Running Wireshark on the client shows it trying and retrying to send a "71 Configuration Request" While the server shows the incoming client requests, but apparently without replying: Given that this is GRE traffic, I think rules out the GRE traffic being blocked. Question is, why doesn't the server reply? This is the Configuration Request the server receives from the non functioning client (meaning no response is sent to the client request): And this is the Configuration Request the server receives from the working client: To me they seem identical, except for differing keys and magic numbers, and the fact that one client receives a response while the other doesn't.

  • Netgear VPN endpoint drops connectivity to single IP address

    - by Justin Bowers
    I'm having a strange issue with one of the networks I manage recently. We have about 14 different networks connected together through a Netgear hardware VPN. Everything has been running fine (other than standard connectivity problems) for a few years now, but I've hit a wall with a problem that's just cropped up at one of the VPN endpoint locations. Our primary VPN network is on the 192.168.1.0/24 subnet and our other 13 networks are on the 192.168.2.0/24 - 192.168.14.0/24 subnets. We run a terminal server on the 192.168.1.0/24 network with IP address 192.168.1.100. Starting Thursday of last week, we had a problem with connectivity of the 192.168.2.0/24 network to 192.168.1.100. When troubleshooting the problem, I found that Network 2 (192.168.2.0/24) still had connectivity to the Internet as well as VPN connectivity to Network 1 (192.168.1.0/24). We could ping and connect to any other device other than the server with IP address 192.168.1.100. Also, none of our networks had an issue accessing 192.168.1.100. I ran a scan on Network 2 after assigning static IP addresses to one of the workstations but received no response from 192.168.1.100 (looking for possibly a new device that someone had plugged into Network 2 that had a duplicate IP address with the server). Asking the staff, noone had reported connecting a new device to Network 2 as well. I then assigned a secondary IP address of 192.168.1.88 to the server and could ping and connect to the secondary IP address from Network 2, but still couldn't access it via 192.168.1.100. I then just rebooted the Netgear VPN Firewall (FVS318v3) and after it came back up, connectivity to 192.168.1.100 was restored. Beforehand, when checking for devices with a possible duplicate IP address, I did run a check for available wireless access points and stations and found none (our wireless is secured via MAC address access control through a WG102 device). I thought that it may have been a fluke for some reason since everything came back up after a power cycle of the VPN Firewall. Things ran fine for a few days until this afternoon, when the problem happened again. One of our users claimed that they had connectivity problems to the server and after connecting to the computer, I found that I couldn't ping the server address anymore. I could still ping the alternate IP address of the server though, so I went ahead and rebooted the VPN firewall again and connectivity was restored. Unfortunately, I can't find anything in the security or VPN logs of the firewall that helps point me in the right direction, so I thought I would go ahead and ask to see if anyone else has any other insight into why we've started having this problem. I am aware that it could still be a device with a duplicate IP address of the server on Network 2, but every employee claim states that there's been no such new device brought in to the network. I know this is a long read, but any help is appreciated! Thanks, Justin

  • UFW as an active service on Ubuntu

    - by lamcro
    Every time I restart my computer, and check the status of the UFW firewall (sudo ufw status), it is disabled, even if I then enable and restart it. I tried putting sudo ufw enable as one of the startup applications but it asks for the sudo password every time I log on, and I'm guessing it does not protect anyone else who logs on my computer. How can I setup ufw so it is activated when I turn on my computer, and protects all accounts? Update I just tried /etc/init.d/ufw start, and it activated the firewall. Then I restarted the computer, and again it was disabled. content of /etc/ufw/ufw.conf # /etc/ufw/ufw.conf # # set to yes to start on boot ENABLED=yes # set to one of 'off', 'low', 'medium', 'high' LOGLEVEL=full content of /etc/default/ufw # /etc/default/ufw # # Set to yes to apply rules to support IPv6 (no means only IPv6 on loopback # accepted).

  • How to allow remote connections to Flask?

    - by Ilya Smagin
    Inside the system, running on virtual machine, I can access the running server at 127.0.0.1:5000. Although the 'remote' address of the vm is 192.168.56.101 (ping and ssh work fine), I cannot access the server with 192.168.50.101:5000 neither from the virtual machine nor from the local one.

  • I have UFW block messages from local network machines, how can I analyse if they are malicious?

    I'm getting a lot of messages in my UFW log, and I'm trying to figure out if these are malicious or just normal. A UDP broadcast is coming from a windows laptop x.x.x.191, and some from our synology disks x.x.x.{6,8,10,11}. I have not figured out which macine 114 is yet.

  • How to prevent certain applications from accessing the internet?

    - by Arun Haridas
    I want to prevent certain applications from accessing the internet. When I was using windows XP I had an application (i think it was Zone alarm) which always notified me when an application tried to access the internet. I wonder if there is an application in Ubuntu which would do the same task. If it is possible, please suggest a gui application. the problem is, my internet provider allows me to connect to a single host at a time, that means no two applications can use internet at the same time. When i checked system monitor it showing me that internet is working fine still my browser cant browse.So i want to kill the other application using the internet to browse.
