bridge filter

After firewall enabled on bridge all clients on related bridge unable communicate with each other. What i am missing here?

Why would you like to run traffic passing bridge through firewall?

Even if you would really like to do it, firewall rules might need to be adjusted … e.g. input interfaces are individual interfaces and output interface might not be known yet (routing decission not made yet).

With bridge firewall on i am able mark packages via mangle for queue tree to prioritise IPTV traffic in VLAN.

You don’t do that using bridge firewall, but using routing functionality, when passing traffic from internal to external zone.

Bridge filtering only applies to traffic within ONE subnet.

Instead of posting different requirements on each post why dont you write a coherent set of requirements.
Functionality you would like to have out of your network, without discussion of equipment or config solutions - strictly what you need people to do (for work or pleasure LOL)
