Dear all, I'm testing my proxy and I'm using mediaproxy for natted client. Everything works fine, if there is a client behind nat calling a public user, mediaproxy works fine. This is true also if there is a public client calling a natted user.
I have some problem when there are 2 client behind NAT.
1. I tryed to test the system with 1 client behind NAT and 1 client behind the SAME NAT (both of client under the same subnet:192.168.10.x). In this case Mediaproxy doesn't work. RTP in direct between clients.
2. I tryed to test the system with 1 client behind NAT and 1 client behind the SAME NAT (with clients under different subnet:192.168.10.x and 192.168.0.x). In this case Mediaproxy doesn't work. RTP in direct between clients.
This is Mediaproxy Debug in the last case:

I am sure of mediaproxy change SDP parameter even in these last cases (I can see on openser debug that proxy send out, for example, a 200 OK with SDP part changed. And xlogs DEBUG show me that openser enters in "use_media_proxy" routine) .
But when I sniff the packet on client side, I see SDP part with private IP !
Any suggestion?

Hi Daniel,
Can u post your openser configuration as well as a complete ngrep trace for the calls you have problems with?

Hi!
Take a look at http://www.mail-archive.com/users@openser.org/msg13000.html
I am not sure it is the same problem, but it sounds a bit like it.
