OpenVPN – connect through a proxy or firewall restriction

 

Sometimes you want to connect to the VPN server at work, at dorm or other institution that blocks VPN traffic by a proxy or firewall restriction.

Examples of such proxy are: Microsoft ISA or Linux Squid

VPN protocols such as PPTP, L2TP, and SSTP are not good for connections where required to provide additional data to the authorization of the intermediate proxy traffic to the Internet.


However, we have a solution, that is OpenVPN client

The first step is to configure the OpenVPN client to connect to our VPN servers.

Configuration examples can be found on our website in the section: CONFIGURATION

After properly installing and configuring OpenVPN client, go to the settings.
