Hello, I am testing Windows 10, but I can't seem to be able to connect to our FortiNet.

Forticlient gets stuch at 98% for a while, then disconnects. I have tried all solutions that worked for me in the past when I had the same problem in Windows 8.1, to no avail.

Is this being worked on?

Thanks,

Tanausu

The upcoming FortiClient 5.2.4 release supports Windows 10. Both IPsec VPN and SSL VPN work correctly.

FortiClient 5.4.0 Beta 3 should also support Windows 10.

renotof,

I saw this when I installed FortiClient to a slow VM. It seemed that the GUI didn't get a chance to refresh.

Hello,

I have similar problem. When I am using forti client 5.2.4 as a ssl client everything seems to be ok but the connection does not work.

I compared routing table after connection to ssl vpn on windows xp and on win 10. There are some differences. On win 10 vpn client added the routes with default gateway which does not exist in my vpn configuration. Therefore I can not ping default gateway from address pool assigned by Fortinet Virtual Adapter.

Regards.

I'm having the same issue that the ssl connection on the forticlient does not work.

If I check the debug logs I get flooded with the following messages:

I solved this exact same issue by disabling ipv6 from the LAN adapter and re-installing forticlient. Maybe reinstalling didn't exactly do anything so just try firstly by just disabling ipv6 by unticking the box in LAN properties.

We have the exact same thing. SSL VPN traffic not working on Windows 10. The solution above did not fixed it for us. What we notice it that there are no mac-addresses learned on the fortissl interface. Same client 5.2.4.0650 works fine with SSL VPN on other OS'ses.

Fortinet, is it a known issue by now? Whats eta on the fix? Beta perhaps?

I dont think Fortinet is listening :(

This problem doesnt seem to have a solution so they are playing ostrich and burying their head in the sand

Well, it seems that problem has not yet been solved after so many months since this threat was opened and thousands of new computers running Windows 10 have been sold to corporations, who really need this to be fixed. Very estrange behavior of Fortinet.

I have repeated almost twice the following event succession:

1) Install ForticlientOnlineInstaler, currently installing 5.4.0.07800 version, only VPN connection.

2) Create the vpn connection

3) Now I can successfully start the vpn connection an unlimited number of attempts (9).

4) I restart the computer and I’m still able to connect several times

5) 2^nd restart and game over. Nothing beyond 98%

What the hell is changed after the 2^nd restart?

You just uninstall Forticlient, restart your computer, install it again and you will get over the same sequence.

Is it that difficult for Fortinet to troubleshot this?

sahins I have had the same problem on Win 10.

Connection succeeds, there is traffic, but you can't talk to the other computer.

Per a friend in the security business, the issue is with the certificate on the computer to which you are making the VPN connection.

Windows 10 does not support SSL as it has been deprecated. Unfortunately upgrading the cert to the new NIST standard will break connectivity for Windows XP machines. Windows XP will soon be practically obsolete, as they will not be able to access any secure websites regardless of VPN.

Hope this helps! It should all come to a head in the next few months. We have had to roll our machines back to 8.1 just to get work done.

FYI, the FortiClient available in the Windows Store is working for SSL VPN under Windows 10 Insider Preview builds!

... and it does accept 2 factor authentication, I hope Fortinet gets this fixed.

It works with FortiToken and RADIUS challenge.
