I want to know what UDP ports and IPs are used for a GoToMeeting call. The call can happen on GoTo Mobile App / Desktop App, on a browser or on any other platform. Minimal Firewall Settings for the GoTo App As per this article, UDP ports45000-65535 and 3478 are used. Allow listing and Firewall Configuration for GoTo Meeting In the parent article, UDP Port1853 and 8200 are mentioned for " VoIP" (and also in-session communication). I am a little confused here. VoIP is used in calls, right ? Can I also get traffic on UDP port 1853 and 8200 when on GoToMeeting call on any platform ? Firewall settings for GoToMeeting I came across two support pages https://support.goto.com/meeting/help/minimal-firewall-settings-for-the-goto-app https://support.goto.com/meeting/help/allowlisting-and-firewall-configuration I want firewall rules for GoTo Meeting. How to figure out which is the latest one ? Solved
