Problem w/ network and dsl

I was wondering if anyone can help me out. I had a tcp/ip network set
up at my office w/ a few computers (win 98) on it, and I would set the
IP addresses myself (10.0.0.10 and so on). When I got dsl I had to
release my ip's and obtain them automatically, I use ZoneAlarm
firewall software so I need to be able to tell it a specific IP to
connect to the other machines. All i have is a modem and a ethernet
hub. I set up the same kind of network w/ win2000 a few years ago and
did't have a problem. any hepl would be appriciated. Thanks
