Part of our standard router configuration in a MUD involves bridging some Ethernet ports, then defining several VLANs on that bridge. Through 6.40.x, it works fine with all our equipment: other RouterBoards, as well as Ubiquiti EdgeSwitches and Dell 5324 switches.
As soon as we upgrade a router to 6.41 or beyond, any Dell 5324s connected to it stop responding or passing traffic, until we downgrade the router to 6.40.x.
How (and why?!) has the behavior of VLANs on bridges in 6.41.x (with vlan-filtering=no) changed from their behavior pre-6.41, that would cause problems with this particular type of device but no others? Does this mean we have no choice but to replace all our Dell 5324s, or to re-implement our configuration at every site to use the new VLAN filtering functionality?
I had kind of hoped that leaving the new feature disabled wouldn't break anything.
