I have 311B fortigate and using firmware version is v.5.2.1. In Policy&Object>Policy> IPv4 is there but it is not configurable on the right pane when selecting it.Right pane is empty. there is no any button active there like "Create New", "Edit" or "Delete" etc.
The same thing is happening to IPv6 too. others are okay.
How can I figure out this issue? Or is there setting I have to enable first?
