Need help pls with a simple PASS-rule.... (Default deny / state violation rule)

[noviceiii]

Dear all

Sorry to ask a certainly very basic question but it drives me mad after an hour of trying... I don't get it to work.
May I ask for a helping hand?

I'd like to allow IGMP traffic that matches
- "LAN" interface,
- source "LAN net",
- protocol "IGMP"
- destination "any"
(I have played with a various combinations).

But the trafic gets blocked by the default deny rule (see screenshot).

Greetings

and then again, it was something completely different.

I had to disable IGMP snooping on the bridge. See here: https://forum.proxmox.com/threads/multicast-bridge-problem.107410/
