I have a 80E cluster that have this problem. SSL VPN forticlient are disconnected every 30 minutes.

I'm sure it's not a problem on Forticlient becasue itìs able to connect to another 80E (not cluster) for about 8hours withou problems.

    Does it disconnect only during periods of inactivity?

    I have similar problem. If I am precise maybe disconnect is not the right word in my case. FortiClient console shows RemoteClient status as connected, but actually VPN is down and my apps cannot access the LAN any more until I disconnect and reconnect the VPN connection.  It happens sometimes sometimes after 10min, sometimes every 2 hours, on average VPN stays connected about 30min. I am using latest FortiClient 6.0.2 on windows 8.1 (64bit) and I am using fast and stable internet connection (fiber).

    Hi Everyone, 

     

    We have a SSL VPN for our corporate users on a Fortigate 5001V (daily average users 10-15).  Everyone internet speed slows down as soon as they connect to vpn.  Below are some examples of speed test without and with vpn.  Please let me know if this is normal expected behavior slow down or if there is something that we can do to improve the situation.  I can also provide tracert if need be.  We do have a manage network so I do not full cli access to the blade, but I can pass any recommendation to our manage provider company:

     

    The issue is more significant and a pain point when users map a server shared folder and they try to save or dowload the file.  The VPN blade is in the west coast and most share folders are also in the west coast.  I do expect some slowness while updating huge excel files in the NY shares drive folders.  Our typical time from vpn or from mpls is always consistent at 75ms from LA to NY (while on vpn or mpls is always at around 73ms), so I think the culprit could be the fortinet 5001v.  

     

     

    100/100  -> on vpn 20/10

    300/20  -> on vpn 30/3

    70/10 -> on vpn 15/2

    175/5 -> on vpn 15/5

     

    thank you

     

    Manuel
