<div dir="ltr">Hi Jens, <div><br></div><div>Stun does not work over symmetrical nat. Please use an utility called winstun and test the firewall/nat traversal of your clients. If they are symmetric, the only way is rtpproxy. Rtpproxy does not work behind a firewall without a patch. The scenario you are trying to create is not an easy to do with both clients and servers behind NAT. If rtpproxy is consuming 99.9% of CPU something is wrong or you have a high number of simultaneous calls. You can also try mediaproxy from AG-projects. <br>
