Google Duo over LGFL

[dekusolutions]

Hi all,

 

I have an LGFL/Adept school wanting to use Google Duo.

 

Ports 19302 - 19309 inclusive are all open UDP

duo.google.com is alllowed through Webscreen

LGFL Bundles are allowed (Allow GSuite/Allow Google Meet)

 

They can ring out externally, the other person receives the incoming call, answers, but then it just sits there connecting, no video or audio on either end.

It also happens when an external caller rings into the school.

 

Ive turned off firewall on machine aswell to test, still the same

 

Im stuck for ideas, and Adept (since taking over Atomwide) are just wasting my time.

Cannot find any other ideas by searching, no other ports or IPs to unblock etc.

 

Anyone experienced this?

I'd ask them to check STUN ports are open. Also go into WebScreen and run a report to see if any URLs are being blocked.

 

If this doesn't work usually the FW Team, if you give them your internal IP address, can monitor the firewall to see what is being blocked.

Thank You!

 

It was UDP 3478 (STUN). No Google documentation mentioned this, only the ports i mentioned above!
