[Freeswitch-users] RTP NAT issue

[Michael Giagnocavo]

Well FreeSWITCH needs to get an RTP packet to know which port/IP to respond to, for the general case. Do a full UDP capture and open it in Wireshark. The VoIP calls flow view will show you RTP streams, too.

Hi Dave,

I've tried the "aggressive_nat_detection" on my internal profile. Restarted the profile and I have this registration:

Contact:        "Test 202" <sip:202 at 192.168.2.100:5062;fs_nat=yes;fs_path=sip%3A202%40<FS IP>%3A37710>

but FS send the RTP to the private IP (192.168.2.100) and not to the public NAT IP.

Is there something wrong?


Best Regards

Been using this configuration for service providers for years, and always works. Everything always works, transfers etc...

Suboptimal solution. you'll break transfers among other things.
