My Ruckus controller and AP are in the same subnet. I'd like to test GRE VPN between them. General purpuse is actually create GRE VPN between controller and AP-s in different subnets, because some of them are located in other buildings connected via VPN over WAN. That makes probably possible to use same subnet for wifi clients behind local AP and as well behind AP-s of other sites. First of all is better to start testing in local site. Is that enough to turn on ""Tunnel VLAN traffic throgh Ruckus GRE" and "Enable Proxy ARP" on controller? These 2 checkboxes doesnt bring GRE VPN up. What should I do more?
