That too is no problem - it just needs to be able to open a port on
the GIAddr. It doesn't matter if the packets come in through a
different interface and are internally routed, or come in on that
In either case, the rule is quite simple, listen using the packet
filters for the raw packets from clients, open a port on the same
interface (ie on the GIAddr) to listen to packets back from the

Obviously, if there was a server on that network then it could double
up as a relay without any extra cost.
