That's for pointing out Walter Snel "hack". Adding his two additional features would not be hard.http://lists.digium.com/pipermail/asterisk-users/2003-October/024968.html
in sip.conf "nat=1" means the _client_ that Asterisk is talking with is NAT'd. We could add a line like below to sip.conf asterisk_interal_network=<network name or address/mask> and a line like asterisk_external_address<FQN or ipaddress> One hitch is DHCP. The asterisk_external_address could change at any time while Asterisk is running when the DHCP lease expires. For that reason I would set up a dynamic DNS service and use the FQN raher then numeric address. But if you have a fixed IP that could work too. inside the code you test for "dest.sin_addr" being within <network name or address/mask> Network name can be numeric address/mask or a "network name for /etc/networks or the networks NIS map.
