PepVpn from AP AC Mini to Balance 380

Dear , For our customer, we need to connect an AP AC Mini with Pepvpn to Balance 380, the Balance must propagate two vlan that are tagged on two different SSID. Our problem is to ensure that the access point WIFI propagate the two networks, the client authenticates the first WIFI network to acquire an ip from vlan 2 while the client connecting to the second network WIFI acquire an ip from this other VLAN3.

How should I proceed in the configuration?

thank you
