I have 2 Max HD2 routers configured as a layer 2 bridge over pepvpn, utilising 4G LTE as the WAN link (at both ends).
I’d like to restrict the traffic/ports (primarily multicast video) from crossing the bridge. I thought this could be accomplished by the incoming/outgoing firewall settings on both routers (eg, block all UDP on the known multicast ports). However none of the firewall settings appear to function/block any traffic. Is this expected behavior with the layer 2 bridge configuration in place, or am I missing something? Running firmware 6.3.2 on both.
The layer 2 bridge approach is highly desirable for this scenario, so I’d prefer to keep it if possible.
