Ah, i see what you're saying now, Wayne: it's true that you can't guarantee that any external firewall rules are working just by testing within the LAN. You'd need to use traffic from an actual external IP address to verify any port forwarding or access restrictions to be sure that they're in place properly.

But that doesn't mean that you couldn't do an effective NAT'ed port forwarding that copes with connections from inside as well as outside the LAN, only that you can't test your external rules properly from the inside.

I'm glad the tip above is useful!
