ipchains, port forwarding

["Andy Schuler" <news mail onemain com>]

I've setup a router/firewall box running RH 6.2 and using ipchains. I'm
wondering if it's possible to forward requests on specific ports to machine
on the internal network. ie, a port 80 request will be passed through the
firewall (int ip 192.168.1.1) to an internal box (192.168.1.5). Any ideas?
Thanks.
