When a packet comes into the box and goes through portfw, it sets up a masq
entry that includes the source/dest of the original packet and the new
destination. The original destination is stored as the masqed address/port.
When packets go back out to the Internet, they are replaced with the info
directly from this table instead of the default address.
This, at least, is what the code is supposed to do. I have never tested it.
