<div dir="ltr">Hi!<div><br></div><div>I'm trying to implement a solution like this.</div><div><br></div><div>WAN - Firewall(NAT) - OpenSIPS(w. rtpproxy (2.0)) - Freeswitch'es</div><div><br></div><div>Main idea.</div><div>Hide all internal network topology to make all endpoints to work like "on single WAN address"</div><div><br></div><div>All endpoints are on FreeSwitch'es. On a Firewall there is port forwarding to OpenSIPS (both SIP and media).</div><div>On which Freeswitch to forward request is decided based on domain name information.</div><div>What I want from OpenSIPS.</div><div>1. Advertise like on external address (done)</div><div>2. Proxy REGISTER messages to Freeswitch (particial, works, but no topology hiding)</div><div>3. Endpoints should work behind their own NAT (particial, with rtpproxy -A flag)</div><div><br></div><div>So, the question is: is it possible to fully hide internal topology in this case and not to do a big manual "total-packets rewrite" work? Cause now it's all working, but while contacting endpoints I see internal IP addresses in Via headers, contact headers, etc.... So, OpenSIPS should act as a b2b, but fully behind NAT and have a proxy capabilities (for REGISTER, SUBSCRIBE, NOTIFY....)</div><div>Just point me on a right way to go ) Which modules to use is right? ) Or may be to use some other ideas as well )</div><div><div><br></div>-- <br><div class="gmail_signature"><div dir="ltr">Best regards,<div>Igor</div></div></div>
