Remote desktop and SAP suddenly became very slow over SSL VPN

[MahmoudAbuzaid]

Dear All,

Hope you're doing well, since yesterday all my users are suffering from connectivity lost for SAP and RDP connection over SSL VPN and when i checked i can see that the ping is very stable but when I try to remote desktop I get the connectivity loss issue.

I've tried disabling and enabling DTLS with no luck

I Also Tried disabling fortiheartbeat in ssl root with no luck

My Fortigate is 200 with fortiOS version v5.6.2 build1486 (GA)

Any Idea ?

Ummmm - I haven't run 5.6.* in a few years on any of my clients, so I don't recall if this was/is a known problem or not at that level of firmware.

I can suggest that upgrading to the most current (at least on 5.6.*) won't hurt, at any rate.  The latest is 5.6.12.  As always, though, follow the upgrade path prescribed by Fortinet.

hi 

Are you still having the issue, because i am.

i have recently updated to version 6.2.7 on a fortinet 80e but the issue still persisted, i noticed that if i disable the antvirus UTM feature the issue is no longer. My clients noted that it is worst in the mornings.  SAP sessions and RDP session gets drops. 

thanks
