Hello all,

I have installed latest Kamailio 3.1.3 on latest ubuntu server. Everything seems to be working well

on my LAN. I can successfully register with local Kamailio IP address (192.168.1.137).

The issue is that I can not run Kamailio on my public IP:

listen=udp:77.XX.XX.XX:5060 
listen=udp:192.168.1.137:5060
port=5060

Kamailio runs behind Linksys WRT54GL router with latest Linksys firmware and DMZ is turned on (192.168.1.137).

Here is the error I am getting when trying to run kamailio with my public IP:

Apr 7 02:57:40 sipbox kamailio[1050]: ERROR: <core> [udp_server.c:400]: ERROR: udp_init: bind(7, 0x82cc6e4, 16) on 77.XX.XX.XX: Cannot assign requested address

Do you have any idea what I'm doing wrong ?

Thanks !
