I have an AP1142 in a remote network with the IP 192.168.0.24. All the traffic that go out this remote networks is NAT with the IP of the router 172.20.1.1. When the AP tries to connect with the controller WLC 4402 (172.16.1.14) its arrives with the IP of the router (because NAT) and the controller can not connect with it. Do anyone knows if its possible that the controller connect with the AP in this situation (NAT). If its possible could you pass me a guide explaining how to configure it?
