With Linux, port forwarding is configured by adding iptable procedures that has a DNAT concentrate on on the PREROUTING chain in addition to a SNAT target towards the POSTROUTING chain. After doing this iptables will use the existent masquerade table to rewrite packages so they're going to get to the desired host in concordance Using the port forwarding policies you supplied. This is comparable to OSX and BSD, even so ipfw is employed. Generally ipfw is now compiled with kernel.
