IPChains rules

["A.Sajjad Zaidi" <sajjad@example.com>]

Im trying to setup rules through IPChains so everything except a few
services are blocked. The problem is that only one port or a range of
ports can be specified. Is there a work around for this?

This is what it looks like now:

ipchains -A input -b -s 99.99.99.99 -d 88.88.88.88 ! 21:22  -p tcp -j
DENY

Thanks,

Sajjad.
