If you plan to use SSL VPN on a PC that runs on Windows Server 2016, make sure to disable IE Enhanced Security so that it can function the way it is supposed to be. Once the disclaimer is accepted, you will be given access to its settings where you can choose between SSL VPN and IPsec VPN. Features and HighlightĪ disclaimer shows up as soon as you run FortiClient VPN for the first time which you must accept to use the software. It is provided for free with limited features and it has no technical support. Thanks to the encryption, no one else can use the data even if someone manages to intercept it.įortiClient VPN is a security product of Fortinet that can be downloaded as a separate software for a number of operating systems, including but not limited to Windows. This security layer ensures that the data sent back and forth in the tunnel is safe. Thanks in advance.FortiClient VPN creates a secure tunnel to access a network from a remote location. I am not an expert with network technologies and VPN in particular but can understand instructions and use required tools. I don't know what else to check so I will appreciate any suggestions where to dig. I also tried to check network packets with WireShark but this is beyond my knowledge. There are no relevant windows events (I checked system and applications log). There are no entries for the time when I reproduce issue. I browsed sqlite db "C:\Program Files (x86)\Fortinet\FortiClient\logs\fclog.dat". it didn't ever work on Windows 10 for me). Also I had to reinstall Windows 10 once but problem reoccurred after clean install (i.e. I had no problems with Windows 7 and Windows 8.1. This problem is relevant only for Windows 10 (before and after Threshold 2).

I tried to make routing table same as without Cisco VPN (it adds routes when connected) bu it didn't help. Same result with disabled Firewall and HIPS (provided by Comodo). Changed registry key "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\CVirtA" as described (removed from beginning).Installed Sonic VPN (it added DNE filter to all network adapters).

It doesn't work in 10 out of the box so I followed this guide.

But there is one important difference related to CiscoVPN. My setup is mostly identical to what I had in previous Windows versions. Reproducing in 100% cases, very easy to catch (but not to find underlying issue with skills I have). When I disconnect Cisco VPN, I can ping network resources again, can connect via RDP ans so on. my PC cant see remote hosts, ping timeouts). When I connect both to Fortinet SSL VPN and to Cisco VPN at the same time, I cannot use network provided by Forticlient (i.e.
