Forti SSL VPN Freezes machines

Is this in in Web-mode or " Tunnel-mode" (when using that ActiveX component) only ? I' m using web-mode only but never had a similar issue - it also shouldn' t happen at all in Web-mode since it' s straight http. -R.

@ red.adiar: This is in Tunnel Mode. Have the checkbox not checked of the clean cache. thanks for your reply, ive made a support-ticket, hopefully it will be solved. Regards,

I solved the problem. Ive changed the auth-timeout setting in the ssl vpn config. Setting the client authentication timeout setting: The client authentication timeout setting controls how long an authenticated connection will remain connected. When this time expires, the system forces the remote client to authenticate again. For example, to change the authentication timeout to 1800 seconds, enter the following commands: config vpn ssl settings set auth-timeout 1800 end - Also when you press CTRL+N in the IE ssl vpn browser window, the machine will freeze or hang, not always completly freeze. Now when i connect to the ssl vpn browser and log in, i can open anything on the internal lan longer then 30 mins, tested it and got connected for more then 60 mins. So al seems to work prefect now :-) Hope this helps, Regards,

I' ve been facing this same problem with the fortigate 60. Although the only time I find it to freeze my system is when I' m copying and or accessing files through a mapped drive over the SSL VPN. If i' m using outlook everything seems to be fine, but as soon as I start accessing a mapped drive it completely locks and or freezes up the system. I saw someone had put a ticket in for this, was there every any fix and or solution? TIA!

There' s a confirmed bug with SSL-VPN to windows 2003 servers (R2) the client will freeze upon connection, if you connect (RDP) to a winxp machine it works fine. Regards, Eric

same problem here. has there been a fix for this?

Not yet...although someone above said they put in a ticket with Fortinet...would be nice to know the status on that :)

I got the same case before while my box is running v3.0mr2..... but now I have downgraded my box to v3.0mr1, and it works fine! Only one user with the freeze case, but I think it would be due to the installed sslvpn adapter on the PC is the new one (v3.0mr2), probably this client will works fine if uninstalled the new one and re-install the sslvpn component from v3.0mr1~ Anyone can share which firmware version are you using with the mentioned freeze issue?

There' s a bug in MR2 that will freeze client PC if connected to a Server 2003 (r2), if connected to a XP machine, that will work. Solution downgrade to MR1 or use Candidate Release MR3 Regards, Eric

I got: Fortigate-200A 3.00,build0318,060630. - Happens mostly on workstations and desktops, did alot of testing with notebooks doing really alot at the same time while connected and got no problems at all. - Also got it while connected to Windows 2003 Servers, all are running SP1, just a complete freeze of the machine with only option left to use reset button. - Support advised me to use different ip range for ssl vpn instead of the same ip range from the lan separated from the dhcp range. - did that ofcourse :-) Now most users do not complain about it cause also pptp server is active in the network, and rdp port forwarding for remote desktop. - intresting to see that more people have the same problem, even read that it was confirmed bug, so hopefully it will be solved. Thanks for reply, Regards, Marcel. -FG200A
