Yes Gordon. I'm using nat=yes and I don't have an ALG enabled
router/firewall. I used the sip debug output on the asterisk(s) and
could see the sdp headers as they were gererated by asterisk, with the
wrong (internal) address on it.<br>
<br>
Asterisk is sending the audio to the correct way, the public IP of
client side NAT. But the client is sending it to the wrong address, the
private IP of asterisk side NAT.<br>

<pre wrap="">Hi all! Do anybody has a full working environment using externip on an
asterisk box behind a nat? I tried with two diferent boxes
(Elastix-1.4.24 e Trixbox-1.4.22-3)and the asterisk do not replace
neither contact, neither sdp headers info with the externip informed on
sip.conf general parameters.
I used these two statements:
externip=XXX.XXX.XXX.XXX
localnet=192.168.200.0/255.255.255.0
Do anybody in list had those dificulties? That's strange because I could
not make this work on two diferent instalations! Trying hard to think
about what's missing.

I have dozens of boxes doing it this way. All "just work".
Have you nat=yes in there too? Also you did port-forward from the router
to the box as well, didn't you?
Often the router will have a broke SIP ALG which will get in the way too.
Turn it off if you can.
