Default Asterisk as SIP client behind router problem

I am usng a asterisk server at home, which is behind one router. This asterisk server is configured as DMZ on the router.

I have two sipphone account config on asterisk server, both needs to be registered, typess are friend.

Now I found that only a certain one of the two accounts can always be reached, both the other account can never be reached, from outside.

Is this related to NAT? Could this be solved by using stun or outbound proxy on asterisk? I have tried but seems no stun support for asterisk.

Default RE: Asterisk as SIP client behind router problem

I would suggest that you place the asterisk server behind the router, and have nat=yes on your trunk,and nat=no for your extensions - I'm guessing your extensions are registering on your asterisk server, and not somewhere else. I am running something similar myself and this is how I'm doing it. Then on the router, fwd the proper ports.

Thank you. It seems everything is ok after setting all nat=yes.
