Missing "Preffered DTLS Tunnel" in FortiClient VPN for Linux

[_Marcin_]

I'm using FortiClient VPN on my virtual machine with Linux Mint (ubuntu).

I'm using NAT mode for my virtual machine and with such settings - FortiClient VPN for Linux (v7.0.0.0018) is not able to connect to remote server.

I'm receiving such error:

NOTICE::Insufficient credential(s). Please check the password, client certificate, etc.
STATUS::Set up tunnel failed
SSLVPN down unexpectedly with error:2
STATUS::Setting up the tunnel
Press Ctrl-C to quit
Clean up...

In my opinion - this message is a root cause:

STATUS::Set up tunnel failed

What is the most funny - in Windows working as virtual machine in NAT mode - with FortiClient VPN (v6.4.1.1519) - there is no problem with connection.

I've noticed a difference in settings between FortiClient VPN for Linux and Windows.

Windows version has such option:

"Preffered DTLS Tunnel"

In Llinux FortiClient VPN there is no such option.

I've noticed also such message in my FortiClient:

"Upgrade to the full version to access additional features and receive technical support." - but there is no "full version" for LInux.

Dear FortiNet Support - how can I purchase full version for linux to have option "Preffered DTLS Tunnel" ??

I can purchase full version - but tell me how should I do it.

Please also provide information why in Linux version of FortiCllient there is no option: "Preffered DTLS Tunnel" ???

Here you can find difference between Linux and Windows versions of FortiClient

Dear _Marcin_,

Could you please have a loot and tell me if it helped?

If not, we will find another solution to your question.

Anthony,

I'm using FortiClient VPN for Linux - and in section "VPN options" - there is no such option:

"Preffered DTLS Tunnel"

Such option is only in Windows version of FortiClient VPN - and from Windows it's working fine.

Problem is only with LINUX version of FortiClient VPN.

You can see details in attached screenshots (difference between "VPN Options" for LInux and Windows):

Windows:

Is any FortiClient VPN Linux version available with Option: "Preffered DTLS Tunnel" ?
