I do not know what type of DSL modem/router you have but if you have
the real cheep modem, get a Linksys router, info available at www.linksys.com
That is what I use. Cost starts at less than 80 dollars US and I have seen
some real deals with them even at Radio Shack.
They will handle PPOE and have the neat function of
having a NAT type of firewall anda DHCP server.

I use the same setup here and I have used just about every
OS there is on my system Mac OS9 and 10, Lindows, RedHat,
Windows 95,98,ME,XP, Net Beta, and 2000
and I have 8-10 computers on my DSL all at the same time.

I hope this helps
