ipchains & VPN connection
I have a linux box set up to masq several internal windows machines on my network. All is working well. I also have a laptop from work that I want to use to connect to my office network via a company vpn setup. Before adding the linux box as the router/gateway, I was doing this via ICS on windows.
At the moment, my vpn connection won't work. The way I think it's "supposed" to work is that I issue a ping command to the office server which then responds with a dialog box requesting user id & password. It then establishes a secure connection and I'm off to the races.
When I connect the laptop to my hub, I can access the internet just fine. I can successfully ping the office server, get the login dialog box, and enter my userid and password. However, I get an error message that the office server can't communicate with my machine.
I am assuming this is due to an ipchain rule that's keeping this type of communication out. The reason I say this is because I had a similar problem with my windows firewall until I set up the office server's IP address as a trusted address. Being really new to the ipchains stuff, how can I set up a specific IP address in the same manner (i.e. trusted)?
I don't know what port the vpn connection is communicating via or any other details beyond the office server's ip address. FYI, eth0 is connected to my cable modem with a static IP and eth1 is connected to my LAN with an IP of 192.168.0.254.
Any help y'all can offer would be great!!!
