How to connect to the University of Tsukuba VPN Services using the OpenVPN protocol

Here we will explain how to make a VPN connection to the University of Tsukuba VPN Services using OpenVPN Client by OpenVPN Technologies, Inc.

A VPN connection method easier than OpenVPN

We recommend you using OpenVPN when VPN connections cannot be made using SoftEther VPN Client and L2TP/IPsec.

• SoftEther VPN Client is easy to use with Windows
  If you are using Windows, then connections will be more stable, faster and easier using SoftEther VPN Client.
• L2TP/IPsec is easy to use with Mac, iOS and Android
  Since L2TP/IPsec VPN Client is attached to OS like Windows, Mac, iOS, Android by default, the initial VPN connection settings can be made relatively easier compared to methods using OpenVPN. For that reason, we recommend you try using L2TP/IPsec first, before using OpenVPN. Some network environment and firewalls will block the L2TP/IPsec communications. In those cases, please try using OpenVPN.
