Priority Settings (advanced) in firewall rule will silently drop the packets

[xtom42x]

when setting the prioriy in a firewall rule allowing traffic (set priority=voice(5), set priority [low-delay]=Voice(5)) the matching packets get silently dropped.

IPv4 Outbound Traffic NATed (for a SIP Trunk)

when i remove these advanced options everything works as expected

OPNsense 26.1.10-amd64

You probably should use Traffic Shaper:

The settings you are changing don't necessarily do what you would expect:

while you're technically right :)

the thing is I imported the firewall settings from an older "silbling" OPNsense where these settings worked (let traffic pass)

so the settings that worked before stopped working silently (was a hell to figure out the reason). Don't think that's how it should be (esp. if you use these options for what they are intended to do)
