I have a RH7.2 firewall doing NAT for me, and I want to be able to reach an
internal webserver from the outside world.  I don't seem to be able to get
iptables to forward the connections forwarded to the server properly.  I'm
trying to use the examples from the IP Masq HOWTO at
http://www.tldp.org/HOWTO/IP-Masquerade-HOWTO/index.html, but they're a
little vague about where the commands should go in the sequence.
