1A First Alternative

Secure OpenVPN tunnel - Windows 10

This manual is meant for 1A-server users.
It explains how you can make a secure connection to your company's network with the help of OpenVPN.
This way you can use your company's network just as when you are connected directly.

Only accounts that are a member of group "vpn" are allowed to connect through a VPN-connection.

If you have installed the old "OpenVPN Desktop Client", please uninstall it through the Control panel. You can find it in the software list under the name "OpenVPN Client".
