My understanding is that OS X PB doesn't work with Enternet 300, which is what you need to use with PacBell's basic ADSL (which uses dynamic IP addressing and PPPoE). If you can afford the $100 set-up fee and the 20 bucks extra a month, you can get Enhanced ADSL which comes with 5 static IP addresses (which works for me, because I've got a 7200/90 and a Linux box aside from my main G4 machine). I haven't actually tried this yet (supposed to be installed next week), but I can't imagine why it wouldn't work, since your DSL router hands out the static addresses to each computer. I imagine I'll have to get some kind of firewall going soon though...
