Hi Max,
You need to inspect the SIP messages and check if your SDP is carrying the proper IP/port for each side of your ALG. Make sure that your openser is providing proper IP in SDP for each network: - private IP in SDP for SIP messages originated by the interface sitting on the private network side - public IP in SDP for SIP messages originated by the interface sitting on the public network side

Hi Ovidiu,
Thanks for responding. As far as I can see, I've done that. I start rtpproxy like this:
rtpproxy -l 10.10.12.4/146.101.250.189 -s udp:127.0.0.1:9000
and when I start openser, It says it's listening on both interfaces.
Restarting openser: openserListening on udp: 146.101.250.189 [146.101.250.189]:5060 udp: 10.10.12.4 [10.10.12.4]:5060 Aliases: udp: lhc-openser.isrighthere.com:5060 udp: lhc-openser:5060 udp: lhc-openser-public.isrighthere.com:5060 udp: lhc-openser-public:5060
This is what I don't understand? It should be working right?
-Cheers Max

If you want to setup openser as an ALG, you will need to configure openser to bind to both interfaces and run rtpproxy in bridged mode (in order to proxy media in and out of your private network).
