Yeah, your experiences with ICS are pretty much universal. Since it renumbers everything and completely changes your networking scheme, it tends to screw up existing networks.

It's actually possible to get the Empeg and your old network working properly and co-existing peacefully with ICS, but it takes a bit of know-how and Blood/Sweat/Tears to get it done.

I think that in your case, for simplicity's sake, you're better off getting a hardware router that does the internet connection sharing. Lots of companies make these... Linksys, 3Com, etc. They can either share a phone connection, a DSL connection, or an ISDN connection. Sometimes you can get them with a firewall built-in.
