I have a symantec 5620 (build 3.0.1) gateway and the admin interface is a little sporadic. I can log in fine but lately it is consistently refusing to display the firewall rules and sometimes also the network interfaces. Most of the options in the left hand side of the navigation tree load just fine but the ones I want in particular, ie. Interfaces and Firewall Rules just won't display.
The firewall itself is running fine and processing traffic, I need to make some changes is all! Anyone had a similar experience?
