Microsoft Teams seems a bit flaky, so I'm trying to priorities the traffic, but there is no documentation on how to set a port range in 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

Use a colon e.g:
but only a single port range per filed so it sounds like you may need 6 rules, 3 upstream and 3 downstream. Please be very careful with your choice of source and destination ports. Generally you only want one of them per rule and what is an upstream Source Port normally becomes a downstream Destination Port and vice-versa.1000:2000

Even that answer is incorrect. It seems you can use anything allowed by the mutliport module in iptables. From the man pages:
multiport
This module matches a set of source or destination ports. Up to 15 ports can be specified. A port range (portort) counts as two ports. It can only be used in conjunction with -p tcp or -p udp.
--source-ports [!] port[,port[,portort...]]
Match if the source port is one of the given ports. The flag --sports is a convenient alias for this option.
--destination-ports [!] port[,port[,portort...]]
Match if the destination port is one of the given ports. The flag --dports is a convenient alias for this option.
--ports [!] port[,port[,portort...]]
Match if either the source or destination ports are equal to one of the given ports. -

2 in the end
(1 TCP and 1 UDP for the three sets of ports) x 2 for Upstream/Downstream
UPSTREAM

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
