9120 Can't join C9800-L-C-K9 as an OEAP

Hello,

 

I have a demo C9800-L-C-K9 and a bunch of 9120 APs that I am using to prove that the controller will be able to replace the 5508 and 3500/3700 APs we are currently using for OE. The APs were able to connect to the controller internally and have been configured as OfficeExtend APs. However, when I brought the APs home, they send a discovery request to the controller and receive a response, but they are not able to join. Here are console log messages from the AP:

Any ideas as to why this is failing?

Please take a look at this guide. Shows you what you need to enable when the ap is behind a NAT.

Yes, follow that guide Scott shared. It should work. I have tested it the other day
