Network ports for GotoWebinar WebApp

Hello Support,   Can you please provide a list of network ports and destinations required for GotoWebinar WebApp?   I have reviewed the Allowlisting and Firewall Configuration at Allowlisting and...

    To chime in here, port 3478 TCP/UDP is used by the new GoTo App or the browser based versions of GoTo for Turn server connections.
    However, there is a fallback to port 443 TCP, in case 3478 TCP is blocked. So its not mandatory.
    We will make sure the main config page gets updated.

     

    The use of the various ports in the context of the new GoTo App is described in detail here (incl. Port 3478):
    https://support.goto.com/meeting/help/minimal-firewall-settings-for-the-goto-app
    This page also details the subnets for which this port is used and lists the minumum requirements for various setups, which are much fewer than listed on the overall firewall page.

    Please be aware that GoToWebinar currently for must customers still runs on the legacy version, which would use TURN server and Port 3478 only for the Web clients, but not for the Organizer app.

Hi Kate,

 

I’m able to replicate issue on Server 2022 and Windows 10.

 

I identified the port by filtering traffic in ‘SYCSENT’ status using the ‘get-NetTCPConnection’ powershell cmdlet and it shows GoTo ip address 173.199.8.74 (see below). When I test outside of corporate network (no firewall blocking), I can see the established 3478 and 443 to GoTo server.

 

Hardware for Server 2022 is vmware and HP laptop for the windows 10.

 

What is InRoom Link and what does it have to do with GotoWebinar? I agree it does have a port range that 3478/tcp is in but in my testing only 3478 shows up and no other port in that range.

 

Can we get confirmation from developers that 3478/tcp is needed for the WebApp?

 

Also, the reason why I’m using the WebApp version on Server 2022 is because the GoTo Opener doesn’ t work on our Server 2022 Citrix server, is there a version of GoToWebinar for Citrix?

      Hello GoTo Support,

       

      Thank you for the clarification. I'll request ports to  be opened and let you know if still getting issues.
