Hard to say because you provided an incomplete config posting.
All the rules work together so if you leave some out, I would only be guessing…
default PVID is 1, and it should be left so.
If you do use vlans, then use vlans and the bridge should do nothing else but be the bridge.
You have not defined the vlans
You have not defined the iP pools
You have not defined the DCHP server
You have not defined the DHCP server network…
You have made your bridge a WAN client to boot, which is in most cases WRONGO!
The WAN is usually set via IP DHCP CLIENT, or other specific menus such as for instances of pppoe.
Take a long hard look at this example I made for another post, similar to yours except they have added wifi on top.

suggest you copy it down and then see what you can do…
As for the persons firewall rules, they are factory default and work.
Much better is the Novice setup described below, very similar but easier to understand and better security.
