I'm setting up a Westell Wirespeed Dual Connect DSL modem to my father-in-laws PC. Everything's up and running fine. However, I'd like to be able to access his PC remotely using VNC, Windows Remote Desktop Connection or PCAnywhere so that I may work on it from my home or from my desk at work. The modem receives its address via DHCP, so I know that will be a variable address. I can work around that. The modem acts as a DHCP server to the pc, delivering an address of 192.168.1.1, with the modem showing it's internal address as 192.168.1.254. I can ping the external address of the modem with no problem. How can I route back through the modem. From an external source, how can I get to the PC residing on a non-routable network?
