Ah, well after the initial excitement that ‘oh an application actually sets
DSCP’ I checked what marking my zoom packets had on the next conference…to
find… Best effort. Crushing disappointment led to this in my firewall box:
#Zoom - connections go to Zoom with dest ports 8801-8810
$IPTABLES -t mangle -A QOS_MARK_F_${IFACE} -p udp -m udp -m set --match-set
Zoom4 dst -m multiport --dports 8801:8810 -j DSCP --set-dscp-class CS3 -m
comment --comment "Zoom CS3 VI"
$IP6TABLES -t mangle -A QOS_MARK_F_${IFACE} -p udp -m udp -m set --match-set
Zoom6 dst -m multiport --dports 8801:8810 -j DSCP --set-dscp-class CS3 -m
comment --comment "Zoom CS3 VI”
With dnsmasq configured to fill the Zoom4/6 ipsets with relevant IP addresses
ipset=/zoom.us/Zoom4,Zoom6
Works a treat.
Cheers,
