Multi-SSID AP not working with Dell X1026

[jes7err]

I've been dealing with this for the last few days: I've been trying to setup a TP-Link AP with two SSIDs on two different VLANs, to connect to my OPNSense box via a Dell X1026 switch.

Seems straight forward, right? Yeah, but I guess I'm missing something because I can't even get a DHCP lease...

1) The SSIDs are respectively set on Vlan 10 and 20. Traffic is expected on 10.10.0.0/24 and 10.20.0.0/24.
2) The AP port on the Dell's switch is set to trunk mode, not general, with vlan 10 and 20 and no native vlan.
3) The opnsense box has two interfaces, each dedicated to vlan 10 or 20, lets keep it simple and start with 20. VLAN20 port of opnsense box in access mode with vlan 20 selected.
4) VLAN created on OPNSense, assigned static IP address to 10.20.0.1 and enabled DHCP server.

VLAN 10 and 20 both have an assigned IP of 10.10.0.2 and 10.20.0.2 on the Dell switch. Firewall rules for the vlan logical interface on opnsense has the same one of the physical interface.

What am I missing here?

Assuming you are connecting opnsense box to the switch using 1 nic port, the port connecting to opsense need to be in trunk mode too.

Trying connecting a pc to the switch and set the port to either vlan 10 or 20. Check if you are getting IP. If not, the issue is the connection from switch to opnsense.

Nope, two distinct ports on the opnsense box...

To have opssnse handle the vlans, the setup is router on a stick. Connect only to 1 interface and set the port on the switch to trunk.
