	Simply put, your system is seeing a specific IP (e.g. 192.168.0.2)
on your local LAN and then latter seeing that said IP is also in use by
someone on your ISP's LAN.  The best solution, IMHO, is to change the IP
topology of your internal LAN to some other off-net IP scheme.  I use
10.1.1.*, subnet 255.255.255.0 for my LAN.  The entire 10.*.*.* network is
resurved for off-net use and should work just fine for your needs.

						Good luck,
