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

    Salut Renaud and welcome to the UTM Community!

    As H_Patel suggests, this is likely due to Anti-DoS/Flooding UDP.  The following commands done at the command line will likely identify which traffic is causing blocks of many packets:

    grep 'UDP flood' /var/log/ips.log|grep -oP 'srcip=".*?" proto'|sort -n|uniq -c
    grep 'UDP flood' /var/log/ips.log|grep -oP 'dstport=".*?"'|sort -n|uniq -c

    Any luck with that?

    Cheers - Bob
