Someone care to pinpoint the cause? I tried to start from clean slate, but it caused some weird behaviour not able to ping or access the router but internet worked fine so I used the factory config.
Once I change the Bridge port PVID for any port they lose connection and can’t access anything. Am I missing some vital setting?
You have no /interface bridge vlan entries. Untagged entries will be automatically generated from the pvid= settings for the bridge itself (the implicit bridge-to-cpu port) and any /interface bridge port entries but you have to define all the tagged entries, e.g. for the bridge-to-cpu traffic.
