Brdige comes with multiple personalities, they are very well explained in this thread. When assigning PVID to bridge, you’re assigning it to bridge port and bridge port is treated just any other port member of bridge (e.g. ether2). Which means that in this case bridge port will be added as untagged to the bridge vlan configuration (unless you manually override that with explicit configuration in which case you risk of messing things).
There are a few problems with your posted configuration:
- ports ether2,ether3,ether4,ether5 are set as untagged members of both VLAN IDs 30 and 99 in bridge vlan configuration. That’s not right, each port can only be member of one VLAN untagged and that should be the one with PVID set (in bridge port configuration).
- your WAN interface is (I guess) pppoe-out1. Not e1-201 and not ether1. So you should set it correctly in /interface list member. This is probably the show stopper about your non-working internet.
