SAT with Pipes
If SAT is being used, for example with a web server or ftp server, that traffic also needs to be forced

traffic is initiated from the outside so the order of pipes needs to be reversed: the forward pipe is the
in-pipe and the return pipe is the out-pipe.

A simple solution is to put a "catch-all-inbound" rule at the bottom of the pipe rule. However, the
external interface (wan) should be the source interface to avoid putting into pipes traffic that is
coming from the inside and going to the external IP address. This last rule will therefore be:
