Each can be used separately, or use them together.
IP Masqerading gives machines on a subnet access to the internet
through one machine which IS on the internet, eventhough
the subnet machines do not have IP numbers known on the internet.
The subnet machines 'masquerade' as the gateway machine.
ipfwadm is a command that administers the ip forwarding rules,
to let certain packets in or out, but not others.
There is a masquerading.txt file in the kernel-source rpm.
See man ipfwadm.
