I have an 1841 router that is translating TCP port 1723 to an MS VPN server on the LAN. This works fine for external users connecting to 126.96.36.199 (WAN interface of router) but users on the LAN (192.168.1.0/24) cannot connect using the external IP address. I'm guessing this has something to do with using the same routed IP for the outgoing translation as well as the incoming translation. How can I configure the router so internal users can connect to the same server using the external IP address? It is useful for troubleshooting.
