What're you trying to achieve?<div><br></div><div>The FS NAT handling should take care of clients that send the wrong (internal) IP in the SDP.</div><div><br></div><div>FS will return its public IP in the returned SDP, they then send from their RTP port to the FS port. FS will see the IP/port the packets are arriving from (the external side of their NAT) and auto-adjust to sending packets to there. You'll see a auto-adjusting rtp log message when that happens. That can't happen until they send media though, which can cause a problem during call setup, eg for ringback.</div>
<div><br></div><div>FS behind NAT would be slightly different, there are multiple options there including the ext-rtp-ip param.</div><div><br></div><div>For rewriting packets it's worth bearing in mind that FS is a B2BUA, not a SIP proxy.</div>
<div><br></div><div>Rewriting the SDP is possible from the dialplan, but I have no experience in that. <a href="http://wiki.freeswitch.org/wiki/Codec_negotiation#Rewriting_SDP">http://wiki.freeswitch.org/wiki/Codec_negotiation#Rewriting_SDP</a></div>
