Possible VPN PIX firewall issue?

Posted on 2005-05-16

Hello All,

I am currently tying to create a VPN connection out of our company and onto another 2000 machine via the internet.
The instructions ask that we create an lmhost file with an IP address on ports_rdp3 and add import this into network properties. Then simply create a VPN reboot.
If we try this at home it connects ok but not from the office. Obviously the main difference is a PIX firewall in the middle but not sure where I should look to confirm this.

My other issue I would like cleared up is if the connection is using the network in the office to jump out (not using a modem) do I need to set the VPN up differently?

Thanks in advance

    which VPN client are you using?  Where is the VPN concentrator that you are trying to connect to?  

    You will need to open up the ports on the firewall that allow the VPN client to connect to the VPN server (concentrator).  For cisco, you open these three ports:
    TCP Port 10000
    UDP 4500
    UDP 62515

    find out which ports your VPN setup uses.

    part 2.
    the VPN client SHOULD detect the connection to the network and use it.  You should not have to tell it to use the LAN or modem.
