Guest wifi over vlan not working

Hi All,

Setup: hap ax^3 as wireless access point, RB3011 as router and dhcp server.
I’m failing to get the guest wifi to work over a vlan (108).

The wifi to my local lan is working fine (ssid 88) but the guest wifi (ssid 73wifi6) cannot connect to internet or the dhcp server.
The hap has 10.2.8.249 as address on the vlan and i can ping the rb on 10.2.8.1 from the hap.
But i cannot ping it from the wifi3 or 4 interface.

I have the idea that I’m missing something in the wireless interface setup.
I’ve compared a lot of video’s and setups with mine but I’m totally stuck so hoping for help here.
I’ll add the hap config to the post. I’m not an expert, just an enthusiast who’s doing his best to do complicated stuff.

You did not add wifi interfaces to bridge/port ?
They should be added as untagged, not the VLAN itf itself.

Once i connect to wifi3 interface its getting added dynamicly to that port, see screenshot, is that what you mean?

You may want to review this excellent guide (and defacto bible regarding VLAN on ROS):

Section related to access point.

Ah sorry, the wored untagged confused me since i could only find it in there but i know what you meant.

But i owe you a big thank you, the settings were as below and after i removed the vlan config from the wifi3 and wifi4 it finaly works, took me a week but learned a lot.
Again thanks!!
