couple of ways to do this - either break up your /24 and route a portion to each AP and do it all static
-or-
set up EoIP tunnels to each AP from your edge router, set up a dhcp-server handing out your publics, and then assign dhcp-client to wlan1. this will give a public to anyone who has a dhcp-client, and if you want to make it a managed public, simply go to the dhcp-server and make the lease static for that customer.
