You didn't mention the VPN server assigned a 192.168.1.x address to the clients. That alone SHOULD make things work, as long as the server is responding to LAN ARP for the client IPs as well as its own IP. As far as I know, it should.
As for adding multiple gateways to the internal machines, it shouldn't be necessary, but it won't confuse them as long as the WAN gateway remains first.
Real stupid question: Is "allow callers to access my LAN" checked in the "accept incoming connection"'s TCP/IP properties on the server?
Also, your client-side config might be wrong, in that it's not using the VPN host as a gateway. Check the client side properties, make sure networking > tcp/ip > advanced > "Use default gateway on remote network" is set. |
