Do you even need these vlans?

Are you doing this for port separation? To keep lan1-4 traffic
separate from wan? DSA does that by default, no vlan needed.

So you can just do

ip link add name br0 type bridge
ip link set dev br0 up
ip link set dev lan1 master br0
ip link set dev lan2 master br0
ip link set dev lan3 master br0
ip link set dev lan4 master br0

and use interface wan directly, no bridge needed.
