I try to create a network setup as shown in the picture. I should say I'm very new to OpenWRT and more advanced network design.
There are some remarks on my specific hardware with VLANs. But I do not yet understand what I should do with all of them. I avoid using VLAN 1 and 2:
My first question is whether the suggested switch VLAN configuration is correct.
When I try to change VLAN 1 to 10 in the switch setting of my router, I loose my internet connection. That is, I adjust the setting on my phone that is connected to the home ssid of one of the access points. OpenWRT reverts the change.
I am able to implement the switch VLAN settings on my access points. Then I can still use my old home ssid.
I can also create a guest ssid on my access points, and connect it to eth0.20. Obviously it does not work yet, because it cannot get an IP, since I am unable to configure my router VLAN (and thus also no DHCP).
Does anyone know what next steps would make most sense? It is a bit hard to try a lot of things, since the rest of the family doesn't like losing internet connection
