VLANs on "switch0" on a AVM4040 block the Internet

Hello, this is the first post in my life, in a Forum so please excuse any mistakes.

I hope that someone can help me, because i tried since two days making untagged VLan Ports on my AVM 4040 with OpenWrt 22.03.0 (r19685-512e76967f).
I tried different Tutorials and also th simply config from her-> https://openwrt.org/toh/avm/avm_fritz_box_4040 .

But every time when i add a VLan ID the connection to the wan brockes. At some tries i ignor this and find out that i can communicate betwine the diverent VLans on eth0(so i thing that i make somthing right), but i dont find a way to communikate to the wan-Port when i change something at the switch0 Vlan.

So the fakts:
Machin: AVM FRITZ!Box 4040
Firmware Version: OpenWrt 22.03.0 r19685-512e76967f / LuCI openwrt-22.03 branch git-22.245.77528-487e58a

the last and easiest thing what i tried is the "Example 1: VLAN on LAN" from https://openwrt.org/toh/avm/avm_fritz_box_4040

so my question now is: can this be a bug or is there something tricky what i dont know?

nice greetings all around Andy

Look for the ipq40xx switch strangeness thread for the background and the pending ipq40xx DSA PR on github for a solution.

Hi slh,
thanks for your answer!
Sorry for my very late response,
i tried to use what you send me but i'm not smart enough for this.

But i tried it one more time and now it works.
I'm not sure what I did differently.
The onyl thing i know is that i found in the Software Manager three addons for VLan (kmod-ipvlan, kmod-macvlan and kmod-sched-act-vlan) an i install it.
So every thing work fine now, thanks agin.
