I have a unique problem that someone with more network expirence than I can probably solve very quick, and I have exasuted myself trying to solve it.

I have a T1 to the internet setup with NAT through a Cisco router. I also have a T1 to a private WAN setup using NAT through the same router. The WAN uses a public address to connect to the server on the LAN, so I have the router forwarding all traffic to this public address to its private (static) address. The router sends traffic destined for addresses in the WAN range to the WAN and everything else to the internet.

Now the remote WAN can connect to all addesses on the LAN, and vice versa. Also the addresses on the LAN can access the internet except the box that has the public (but forwarded) address. This presents a problem because that box runs a VPN server that the WAN clients use. So WAN clients can access the LAN, but no internet.

I know thats a brief description of a complex problem, but since I don't know exactly where the problem lies, thats just a brief overview. Anyone have any ideas?

Did it ever work, or did it just stop?

What address are you using for the default gateway on the VPN box, and / or what static IP addresses are you using to/from the gateway router?

What are the static NAT addresses / ports you are allowing inbound (or forwarding)?

Gotta know ...
