My motivation in continuing this thread is that unless macports users are rare in Aussie (how sad that would be) then other macport users are certain to have the magic big T$ modem. (T$ is joke reference to Telstra)
I do not use the modem wifi, apple do not play nice with furren AC modems (my tests are 5Mb / sec close to a tp link and 35Mb to an airport using my macbook)

Any out going packet will be NAT’d and allowed back
Any intruding packet will not be NAT’d and dumped by the router.
There is no pathway from the internet to any of mymachine unless the packet is ESTABLISHED, RELATED

The best answer that I can find is that if you have and infected machine the firewall prevents it calling other machines.
Well my network is linux and mac machines only, so I guess that is of little concern
