[Asterisk-Users] trying to get trunk to register with * behind NAT

[Jim Sturtevant]

i've got * and phones in small home network all behind NAT. Outbound to
iconnect proxy works great. Now to get in/out working with another carrier.
Carrier2, Commpartners, i have working with one of the phones and a soft
phone without * just fine.  
 
Next I register the phone with * fine. Create a trunk, but it the trunk
fails to register... help 
 
I'm getting the following msg during registration: 
to 66.218.79.147:5060 
Retransmitting #5 (no NAT): 
REGISTER sip:xxxxx.net SIP/2.0 
 
SIP.CONF= 
; Note: If your SIP devices are behind a NAT and your Asterisk 
; server isn't, try adding "nat=1" to each peer definition to 
; solve translation problems.
