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)

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

Since my firewalls don't have direct internet access, I had added the proxy environment variable as shown here so I can download updates.
https://docs.opnsense.org/development/backend/configd.html#extending-the-environment

That worked fine, but it broke the HA synchronization.

That setup is very close to mine (#14) - proxmox VMs, no internet and proxy - so the proxy settings is likely the culprit to look at

I ran into the same issue.

In my case the WebUI is not and has never been changed from the default.

A tcpdump on the primary showed no outgoing Traffic (except pfsync) to the backup at all.

Switching from unicast (for pfsync) to multicast and back didn't change anything.

Reconfiguring the HA settings completely via web form didn't change anything - no outgoing traffic to the backup.


had to switch back to a 24.7 snapshot
