[OpenSIPS-Users] two UACs behind the same nat

[Nick Chang]

Hello 

Opensips don't behind the same NAT with UACs.

Opensips (i.e., 10.10.12.111)
UACs (i.e., 192.168.4.31 & 192.168.4.131)

It's my Network map
(192.168.4.x)UACs <--> Same Wifi <-> internet <-> Firewall <->
Opensips(10.10.12.111)

Thanks
Nick

If OpenSIPS is behind the same NAT (i.e., 10.10.12), the you don't need the
nat fixups or even the RTPProxy stuff. Try commenting them out and checking.
Also, are you "rtpproxy_answer"  in the reply route?
Finally make sure you are starting rtp proxy correctly:

rtpproxy -f -s udp:192.168.2.5:7789 -l private/public -m 20000 -M
40000 -u root root -F -d INFO LOG_LOCAL0_

Hope this helps,

Nick.
