Will have a go in the next few days, Thanks for the help!

QoS uses packet marking. Have a look at "iptables -nvL -t mangle". If you can use selectors in iptables to select packets on DSCP markings, you can try marking them in the same way as QoS does. This "should" then force them into the QoS buckets.

I can't do much about the UI. Personally I think it takes far too much real estate.

Can I point out you can simplify the rules just by using the range 50000-50059 so you only need 4 rules, TCP/UDP inbound and outbound.

DSCP and Bandwidth Manager

Right having sorted MS Teams, I was looking at Zoom and DSCP.

Obviously DSCP has more levels but is trying to do the same thing, is there a way to map the DSCP levels into the 7 buckets of the Bandwidth Manager, or better rewrite the Bandwidth Manager to use those DSCP markings but have a better "UI" so that you can plop things in the right bucket.

Basically Zoom uses the "better" approach of marking the traffic at particular DSCP levels rather than banding ports which you then prioritise like teams,

Any thoughts appreciated

It seems to have helped though frankly Zoom has no such problems or does not report them

Can I moan gently about the UI though, having two lines for each rule is wasterful and means I can't easily cut and paste the text in to here

Right thanks for the pointer, I missed it was a ":" not an ",". Now to see if it helps. Its quite annoying as I have a decent home connection of 80/16Mbps and Zoom copes fine without help good to know that Microsoft still can't write software!

How do I set a port range for Bandwidth Manager

Microsoft Teams seems a biot flaky, so I'm trying to priorities the traffic, but there is no documentation on how to set a port range tin Bandwidth Manager, Teams use 3 port ranges so I'd rather not enter 120 rules (1 for each port upstream.downstream)

I can't be the only one in this time of need wanting to do something about QoS specifically for Zoom (which seems to work robustly) and Teams

Cheers
