John in Kansas or whoever is game to answer,

I'm planning to get a router to use with my system as a sort of bunker behind which my firewall will hopefully be obsolete. Or is this really the case? I've read that routers have their own IP addresses different from the computer behind it, essentially shielding the computer. I'm going to have a couple of computers here one of these days, so will need to to hook all up to the DSL, using the router. Is this still true, though, that it acts like a barrier to some attacks and such?
