yes, you can change that range in switch.conf.xml but you need your firewall open some ports anyway to get it work. On Tue, Dec 19, 2017 at 8:58 PM, Pascal Hari <Pascal.Hari@csa.ch> wrote:
Hello
I’m new to FreeSWITCH and made a setup where everything is behind the same NAT. I have a linux debian 8 server where FreeSWITCH is running on and I’m able to connect different clients (SIP and WebRTC). I’m using the demonstration configuration which come with the FreeSWITCH installation. I mostly followed the instruction “Quick Start FreeSWITCH Demo With Verto Communicator <https://freeswitch.org/confluence/display/FREESWITCH/Debian+8+Jessie#Debian8Jessie-Scriptinstallfreeswitchdemowithverto_comunicator>” but used apache2 instead of nginx.
Now I want that same setup but on a server in the web with public IP. I’m running a linux debian 8 in azure and installed everything accordingly to the “behind the Nat” setup.
I use real (trusted) certificates and can reach the WebRTC client over https. If I’m in the public network of our company I can log in, dial a number and connect to FreeSWITCH (according to the dialplan). If I’m in the corp (internal) network of our company I cannot log in. I only get the message “Waiting for server reconnection”. Even in FreeSWITCH (fs_cli) I don’t see a request.
For me this sound like a firewall issue and many post say to open ports (16384-32768, 5066, …). I don’t have this option because I can’t change our companies firewall. And I’m anyway looking for a solution to provide a WebRTC client which can be used in a normal company network with relatively strict firewall rules. Workarounds like VPN-tunnel are also not a wanted solution because I want a really easy setup on the client (WebRTC) side.
Am I missing a step? Is my guess with the firewall right or could it be something else? Is there a way to configure FreeSWITCH and verto communicator to use other ports?
Thanks already for suggestions.
