Hi All,

    I am using iptables as my firewall, router, with masquerading.
I need to forward a particular IP address from the Internet (eth1)
to a particular PC behind my firewall (eth0, 192.168.255.xxx).

    Would someone show me an example of how to do this kind of
a port forward with iptables?

Many thanks,
--Tony
