I just installed CCA 3.1.1, and I'm trying to access the NAT features on a UC520 by going to Configure then Security then NAT. When I click on NAT, it starts loading security related data. The progress bar goes almost to the very end, but then it just hovers at the very end. The bar is one space away from the end, and it switches back and forth between one space away and two spaces away, but it never actually gets to the end. After 35 minutes, it's still sitting there saying "Loading security related data".
I can get to most of the other features, but nothing in Security.
