WLC ACL Notes
There are some limitations about the ACL’s at a WLC.
You can configure max 64 filters with 64 rules.
If the source AND destination is any, then the direction is also ANY.
If the source or destination is NOT any, then the direction must be specified.
The direction is faced FROM the controller.
So inbound means : From the wireless client TO the controller and
Outbound is : From the controller to the wireless client.
There is an impliciet deny at the end of the ACL.
