I installed 7.1 and IPChains is there but only as a module.  They each
(iptables/ipchains) have there own startup scripts too.
You should be able to just insert the module and use ipchains without a
problem.
IIRC it was configurable in the installation.  Mine actually used ipchains
by default.
2.4 did rewrite it all but ipchains is still available as a module.  I think
the 2.0 kernel filter is also available as a module.  IPFilter?
Or you could just upgrade to iptables and join the truly elite. ;-)
