In verto.conf.xml, there is a param  for ext_rtp_ip, but it was commented out.

<!--  <param name="ext-rtp-ip" value=""/> -->

I tried to uncomment this param and set it to the FS external IP, but it dd not fix the problem..

You must set ext-rtp-ip in verto.conf.xml (can't remember the variable name now from cellphone. Check into verto.conf.xml)

Hi all,

I have been tracking down why my FS verto video conf demo setup not working. Now I believe the reason is my FS server is behind a NAT. My previous posts may be misleading now, so I am creating a new thread. 

Some evidence I saw:

1) In the SDP dialog, I saw my FS server's internal IP got used, rather than its public IP, for example

Dialog 6c62f631-469c-a2f0-e484-6e9cfcda7eedANSWER SDP v=0
o=FreeSWITCH 1444254094 1444254095 IN IP4 10.240.15.244
s=FreeSWITCH
c=IN IP4 10.240.15.244                     <=============
t=0 0

2) Also, in wireshark , I saw my client is trying to send STUN packets to the FS server's internal IP,

450 18.252726000 192.168.1.7 10.240.15.244 STUN 158 Binding Request user: mlvLvmDzCphyQYz5:N3MZoB99aGiAZotr

So now my questions are Will the verto video conf demo work when the FS server is behind NAT?   If so, could someone help me with the necessary config changes and etc.?

Thanks so much!

Tao
