Help understanding Aruba controller + APs, and how it relates to IPv6 and also VLANs?

1. IPv6

Our ISP provides IPv6 through prefix delegation.

The edge router is running pfSense 2.4.4-p3, and the switch is a Ruckus 7150. I have an Aruba 7030 mobility controller plugged into the switch, as well as Aruba APs. The controller communicates with a remote Aruba mobility master hosted offsite.

For wired clients plugged into the Ruckus - they successfully get a IPv6 address - however, wifi clients do not. Is there something special I need to do on the controller to let it pass through IPv6 addresses to wifi clients?

I vaguely remember there was a question in the controller full-setup, asking about whether I wanted an IPv6 address for it - not sure if related, but I believe I answered no at the time - is that related?

2. VLANs

I don't have VLANs configured in this network currently. However, I'd like to introduce them.

The Aruba 7030 was configured just to use VLAN 1 - and I suspect that's what everything else is likely defaulted to.

However, for wifi clients connected to the Aruba AP - how does VLAN-ing working here?

Do the Aruba APs need to be connected to VLAN trunk ports? (I would have thought no, due to the GRE tunnel - but could be missing something here).

Does the Aruba mobility controller need to be plugged into a trunk port?
