Hello, we have a FG100D and since the latest fw-update to 6.2.6 we have strange problem with our SSL-VPN connection. Everything seems to work except Outlook. Outlook (versions from 2010 - 365) connects to our Exchange 2010 server. With some users it works without any problems. With others it simply stops working - then an error message like this appears - no connection... Folders cannot be loaded... and Outlook does not open, or Outlook opens and there is 'No connection...' in the bottom right corner

But after a few hours it suddenly works again - same users, without intervention. A connection to OutlookWebApp is always possible, in all cases. The VPN is configuered in the following way:

The split tunneling works well. But the Outlook error drives me crazy.

Has anyone an idea? Or can anyone help?

kind regards

Hi,

There is an issue with IPSec VPN in the version 6.2.6. Workaround I know: upgrade to 6.4.3 or reboot in the last version you used (change boot flag - see "exec set-next-reboot" command).

https://docs.fortinet.com/document/fortigate/6.2.6/fortios-release-notes/236526/known-issues

BugID 668554 and 610203.

Regards,

Philippe

Thank you for your tipps.

We have a FG100D - the 6.4.x Software is not approved for the 'D' Version.

And also we have a problem with SSLVPN, not IPSEC - but as far as I can see there are also bugs in the SSLVPN, so I will go backwards in firmware and hope it will fix this annoying matter
