I’ve spotted a bug today.
I want to add a new rule for an application under Firewall-> Advanced-> Network Security Policy and I select the application (as seen in screenshot 1) and I click Add from the right panel. It results the following window: see also screenshot 1. Trying to add the rule gives an error saying that this application already exists, etc and the rule is deleted.
When I select the application and I right-click it and select Add I receive the following window (see screenshot 2) and I can safely add the rule.
this is a bug but it is the other way round :P.
The add button from right-click popup work the same way as the edit button (select is disabled).
Maybe they should rename those “Add” to “New” and make them show the new rule dialog (select is enabled)
