Hi,
I have 2 NIC's but the secodn one is not used
The opensips is listten only on eth0 with public IP and default route
So the rtp is not in bridge mode

Andrei

Hi
Does your opensips have two network interfaces, and does rtpproxy
works in bridge mode ?

Hi,
I have installed Opensips 1.9 on debian 6 using the default
config for residential with NAT
My topology is:
UAC ------ ROUTER+FIREWALL --------[ INTERNET ]---- OPENSIPS
----- ASTERISK
UAC is behind NAT 89.xxx.xxx.xxx
Opensips and Asterisk has Public IP's
I'm facing the following issue:
The invite from UAC is announcing his audio port on 4000
Because is not NAT detected the asterisk is sending the rtp media
directly to 89.x.x.x:4000 and no using rtp_proxy
Because the firewall is blocking the RTP port 4000 coming from
Asterisk's IP there is no audio on the UAC side
IF I comment the line #if (nat_uac_test("23")) all the traffic is
going to rtp_proxy and audio is working fine.
Is there any way to solve this ?
route{
force_rport();
if (nat_uac_test("23")) {
if (is_method("REGISTER")) {
fix_nated_register();
setbflag(NAT);
} else {
fix_nated_contact();
setflag(NAT);
}
}
