Thanks for the advice, I guess all I am really needing to do (I am on a cable modem, at&t@home that is) is to setup a local I.P. address...? Ideally I was thinking that I could have some kinda routing table setup that would know which I.P. addresses are local and others would default to outside internet... but... I guess one would need a router for that :) I will try just setting up a local I.P. address (a 192.168 #), thanks for the help.
