weird problem with url filtering

[heisenberg]

Hello,

I've got the bad idea to go with fortios 6.0GA on my 100E, the problem (well one of the problems) is that when I try to filter url category in one or more firewall rule other (completely non related) rule start to disrupt the service (eg. you cannot start anymore connections between client/server)

I've done cli debug (with fortinet support too) but the problem is "weird" but not known.

Is there anyone of you there that is suffering of the same issue?

Best practice is to upgrade away from the first few versions in any firmware release chain. The bugs are plenty and the newer ones (usually) mitigate those bugs and sometimes security holes.

it was a new device and came preinstalled with that.
