-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I have these settings in my sip.conf: [general] nat=yes canreinvite=no externip = tinloaf.dyndns.org localnet=192.168.0.0/255.255.0.0 (if you need the complete sip.conf i can put in on some webserver) Now I use my asterisk on a NATed box with the IP 192.168.1.100 as an outbound proxy for a SIP-Softphone in the same network (running on 192.168.1.3). Asterisk relays all SIP messages, but I would expect it to include my public IP (tinloaf.dyndns.org) in the VIA-headers. This is how outgoing packets look like (The lines starting with U or # are from ngrep): ============================================ U 2008/02/02 22:05:48.730998 192.168.1.100:5060 -> 69.90.155.70:5060 INVITE sip:613 at fwd.pulver.com SIP/2.0.
