My experience with SIP, Asterisk and more than one NAT in the path is not a good one. For example, several of my SIP hardphones refused to work behind a dual-NAT Phone (10.10.0.201) - NAT - internal net (192.168.174.0/24) - NAT - Internet - Asterisk where everything else worked as usual. Admittedly multiple NATs are not necessarily a good idea to have, but that was a customer's network, not mine ;-) Also quite regular setups like Phone - NAT - Internet - NAT - Asterisk and 2 Phones - NAT - Internet - Asterisk without NAT (One of those phones calling the other). might work - or just be a source of trouble. This also seems to depend on the cooperation of the NAT device; some work better than others. IAX seems to handle NAT issues much better, in my experience, but I did never have an IAX hardphone.
