RDP Sessions Dropping
I have about 60 - 70 users who connect through a RD Gateway to RD Session Host servers in our datacenter. The traffic passes thru and is scanned by our FG201E's which are set up in a HA cluster. Two weeks ago I upgraded to FortiOS 6.2.2. Shortly after that we started noticing that we have instances where 20 or so of our total users have their sessions disconnected from the Remote Desktop hosts. This morning for example, out of 44 users that were signed in, 20 were disconnected. All 20 of these user sessions were disconnected at virtually the same time (within 3 seconds).
I am not certain that any of this is directly related to my recent firewall firmware upgrade, but the timing of this issue seems very suspicious. Has anyone experienced a similar issue? Any ideas?
