UTM and Discord video/audio

Renaud Schweingruber

Hello,

I'm running an SG115 with 9.705-3 and I've been experimenting very bad audio and video quality on Discord. Even by disabling most services (IPS, WebFiltering, etc.), I still get it. I'm on a 1GB/100MB fiber connection on a 1GB LAN. As soon as I switch my computer to 4G connected to my mobile phone, I get a cristal clear video and audio quality from Discord.

Is Sophos aware of this ? Is there a workaround possible ?

Best Regards

Renaud

    I've found the following with Web Protection - Application Control. Sophos wrongly detects Discord RTC Audio connections as the app "imo.im" (a messenger app unrealted to Discord).

    The log shows this:

    Application-Control-Regel-Nr.12 imo.im a.a.x.y:52695 > 213.163.95.154:50006 len=301 ttl=127 tos=0x00
    Application-Control-Regel-Nr.12 imo.im a.a.x.y:52498 > 5.200.14.184:50002 len=315 ttl=127 tos=0x00

    After I've whitelisted "imo.im" in Application Control for all my hosts running Discord, the constantly repeating audio drops no longer occured. I'm back to crystal clear group conferencing.
