You need to define two IP pools for two types of dial-up clients, and define
different routing policyes depend of subnets. For example user A gets
IP from IP pool 1.1.1.0/24 but user B from 2.2.2.0/24. And your host have
a following ipchains config:
ipchains -A forward -s 1.1.1.0/24 -j REJECT # We wont forward for A users
If I'm misunderstood the question try again, but [EMAIL PROTECTED] is
preffered place for this.
