Everything Instant On

Hello i look for a solution for building up a wifi network with serveral ssid:
I wnt setup 2 or 3 SSID´s wich shoiuld be routed over a vpn Gateway (Nordvpn or something other). The VPN gateway´s could be realized over a rasperry pi or something like that - it must not realized over Aruba instand on. Our ISP is a ds-lite ipv6 fiber provider in germany (deutsche glasfaser). Is it possible to route the ssid´s with switch to the gateways when i setup some vlans on the pi and plug it in to the switch? 
Whats up actually withh ipv6 support on aruba instnt on?

Should be possible to do that in a first "small" solution with your desktop AP wich have 4 Gigabit RJ45 ports?

Have someone some ideas for me how i can these realize ?

Thanks for any input!

@faximan Our Instant On AP's and switches support VLANs and can support up to 8 SSID's. We do not support IPv6. 

will ipv6 comes in further updates? In Germany it´s hard to get ipv4 if you get a new fiber or cable connection.....
