Helo :) I'm new to FS but not to linux. I've sucessfully install FS into a centos 6.2. But I have an issue. Server has 2 nics: venet0: 10.9.19.5/16 eth0: <public IP> when starting fs, it listen SIP (5060/udp) using venet0. Phones can register and they talk each other. However, we are using an external GW and that fails. Doing a depth analisys I've realized that the reason is that because venet0 is being used, SIP payload has venet0 within but server IP is eth0's so this is tipical mitchach. I've sucessfully configure in vars.xml the local_ip4 (or whatever it writes) to use public IP. but after that no phones are registering. (before anyone says, yes phones points to public IP of course). Nmap reports that SIP (5060/udp) is listen by eth0 but when I got phone SIP, i only get Registering request without an answer. I really need to make this listen in eth0. What suggestion do you have. Please void telling me to turn of venet0 (not possible for politics). TIA
