Very slow or non-functional GoToMeeting, Microsoft Teams, etc.

ken9000

We have only a few users in the office but they are reporting very slow performance of audio/video conferencing platforms. We have a ton of bandwidth so that's not the issue. The same meetings are flawless when joined from home. This happens with the conferencing apps themselves or their browser-based alternatives.

I have a ticket open and the support tech has tried traffic shaping but there doesn't seem to be any improvement. Again, we have a ton of bandwidth and very few users so that shouldn't be necessary.

We obviously need to get this fixed before people start returning to the office.

Any ideas? SFOS 17.5.12 MR-12

    For anyone experiencing a multitude of weird dropped communications issues like us, it appears all UDP traffic (including streaming audio/video, RDP, VoIP, etc.) through the firewall is affected (drop-outs) when what should be completely unrelated IPSec VPN connections made to the firewall via Sophos Connect clients.

     

    So each time one of our 350 users connects or disconnects their Sophos Connect client, all UDP traffic currently streaming through the firewall drops for potentially several seconds for all users trying to view something. I have no idea why these things are related and there's actually no evidence of this in the logs but running the "set-vpn" disable command found in this KB article seems to have resolved it. https://community.sophos.com/kb/en-us/127785

     

    It's still unclear on what the longer-term ramifications for disabling this might be as I haven't received a straight answer from support.

     

    Anyway, the magic never stops with Sophos XG!
