Hi, I think you can use just about any router, but I am definately the last one to confirm this as I have ever only tried it on one.
I have the Telkom 5102G router (4-port etc), and I have two accounts on it, as you describe.
Be warned, this question is often asked on this forum so some of the guys may be a bit short with you
In my sig, you'll see a link to "Route Sentry", click on it and read up on it. Route sentry is an application that allows you to have two simultaneous ADSL connections on a single router through a single ADSL line, and has a setup so that local traffic and international traffic are directed through the relevant correct account. It does require something called RASPPPoE, check out
www.raspppoe.com for more info on that.
I can say that Route Sentry works on Window XP Home and Windows XP x64 Pro, and RASPPPoE comes in a 32-bit and 64-bit version, so this setup is theoretically possible on 32- and 64-bit machines. (I have it working on x64)
Best advice - search this forum for the key words "route sentry" and see what comes up. I have also written a
help-out for others with the same modem as mine, and there was some other input that was helpful.
Feel free to PM me if you have questions, I'll help where I can
