Bridge everything except one specific VLAN

RouterOS General
1

Hi

I would like to know if it is possible to bridge all packes from one port to another, except packets from one specific vlan. This specific VLAN should have an IP on the router itself.

The problem is, that if I bridge two ports together, the router also bridges the VLAN I want to use for the router. I need to exclude it from the bridge.

Any Ideas?

I just found a way to make this work. I just configured the VLAN on the bridge. But now I have the problem that I also see the tagged Packets on the bridged port. Is there a way to filter these packets?

Create the vlan interfaces on each physical int. Then add them all to the bridge as ports

This should work:

/interface bridge filter add chain=forward mac-protocol=vlan vlan-id=XXXX action=drop

You may want to specify in-bridge, in-interface, out-bridge, and/or out-interface; if you are doing other bridging on the same device.
