Sophos SSL VPN Connection

Hi RDM Community =)


the Sophos SSL VPN Client is a bit customized OpenVPN.
I set up an entry for connecting with this VPN simply via importing the .ovpn-File. The Connection works perfectly, when the openvpn-GUI is NOT started, but when i want to close the session there happens nothing.
I thougt i can kill the two processes with

"C:\Windows\System32\taskkill.exe /im openvpn.exe /f && C:\Windows\System32\taskkill.exe /im openvpn-gui.exe /f"

In the normal cmd.exe it works great, but when i try to do the command in properties -> events -> before connect/disconnect -> command line there happens nothing. There simply appears a cmd for a millisecond and then the VPN Client says that the SSL VPN GUI already has started =(
Have someone expierience with the Sophos SSL VPN Client?

Best regards
