Below is my network setup. Using a Wireless Lan Controller and a Lightweight AP as its end point. Between the Router and ASA is an IPSEC tunnel
From my AP segment, i am able to ping to my WLC. Apparently the AP need to pass udp traffic to register itself to the WLC. Unfortunately i got this error msg
IPSEC: Received a non-IPSec (protocol=udp) packet from 172.16.8.4(AP) to 172.16.52.2 (WLC).
I have already allowed ACL of any any udp connection & also enabled split tunneling to include AP's traffic.
What did i miss out?
