I�m wondering if there is a way to comunicate UA agents betwen them that are behind the same nat, they are working perfectly with the outside world (I�m not having problems with Nat traversal), but they try to send the RTP and RTCP data to the aparent public IP that they are registered in the Sip Proxy, and of course, the multimedia data isn�t processed by the router because the destination IP is the one asigned to the WAN interface of it and it sees it in the LAN interface. I�m thinking that maybe the Sip Proxy (ser 0.14) isn�t the problem, maybe the infraestructure is not enough, so, is there anything that you could answer me tha guide me in this scenario?
I�ll be grateful for any information you could give me.

I am also looking for a way to determine if two UAs are behind the same NAT. I have found that if I do not force rtp_proxy between two UAs known to be behind the same NAT, the call is setup and torn down through SER and RTP is sent directly between the two UAs. This is how I want to call to operate. I just can't see a way via SER's scripting language to make a decision based on the src_ip of the initial request and a portion of the URI domain, which in my case is the IP address of the NAT.

You can check if the src_ip and the r-uri's ip address are the same. Just make sure this is done after lookup() and before being forwarded. This method has lots of limitations. Check the archive for more discussions. But most of time it is sufficient.
