Hi,
We have 3pcs AP 105 ,a few pcs remote AP and one controller 620. Previously, we installed the controller and 2 AP 105 in the same Office LAN, now we move the controller to the data center. In order to maintain the current ip addresses, we use doulbe NAT on both site firewalls, and create a site to site VPN. Now both sites use the ip address 172.16.1.0x/24 , and office lan nat to 172.16.10.x,/24 data center lan nat to 172.16.20.x/24. So the ip address of controller in data center is 172.16.1.10, On APs in office ,we set the master controller ip address to 172.16.20.10, the AP in office can connect to the controller (site to site vpn) and registered on the controller, but the LEDs (Ethernet, Wirelesss) on the AP shows "RED". And the client pc can see the SSID, but cannot get the IP address from dhcp server ( on controller). Pls advise what are the possible the cause. The "RED" LED means "GRE" tunnel not working fine ,right?
Thanks a lot in advance.
