[ale] IPCHAINS

[Jonathan Rickman]

Without further details about your specific setup or skill level, I
suggest reading the man page for ipchains as well as ipmasqadm so that
you'll be ready to answer the questions that will probably be asked. Once
you're armed with that basic knowledge email me off-line and I'll give you
a quick class. We'll CC the pertinent stuff to the list. Or...if I totally
misunderstood you and you are a true kung fu master looking for a quick
tip, give this a shot.

after enabling ipforwarding...and assuming you have the mfw module.

ipchains -I forward -p tcp -d 192.168.0.1/32 -s 192.168.0.2/32 22
ipchains -I input -p tcp -y -s 0/0 -d 192.168.0.1/32 4000 -m 2
ipmasqadm mfw -I -m 2 -r 192.168.0.2 22

or something to that effect...that's off the top of my head so double
check everything.
