How to connect to the University of Tsukuba VPN Services using the MS-SSTP VPN protocol

Here we will explain how to connect to the University of Tsukuba VPN Services using the Microsoft SSL-VPN (VPN over HTTPS) Client that is an accessory to Windows Vista, 7, 8, RT.

MS-SSTP (Microsoft Secure Socket Tunneling Protocol) is a VPN protocol that implements the Microsoft-developed PPP over HTTPS (SSL). Since all communications are made over TCP, they can pass the firewall easily. SSTP does not have a very fast communication speed, however, its merits include the built-in client functions in Windows Vista and later OS, and that the initial configuration is very easy.

Connection Parameters of SSTP

If you already know how to make settings in Windows, you can enter the following connection parameters and connect with SSTP protocol.

  If you are using Windows, then connections will be more stable, faster and easier using SoftEther VPN Client.

On this page, we will explain using the Windows 7 screen as an example. The basic setting methods on OS like Windows Vista, Windows 8 or later are the same, however, some operations are slightly different.

How to set on Windows (SSTP)

1. Initial configuration (Only once the first time)

Right-click the network icon in the bottom right of the Windows screen and click "Open Network and Sharing Center."

After the network and sharing center is open, click "Set up a new connection or network."

Select "Connect to a workplace."

Select "Use my Internet connection (VPN)."

Enter "campus-vpn.cc.tsukuba.ac.jp" in the "Internet Address" field.

When a screen to enter your User Name and Password is displayed, enter the fields as follows.

After entering your password, check the "Remember this Password" box and click "Next."

When you click "Next," a 10 to 30 second animation segment will be displayed, and a VPN communication trial run will be conducted using SSTP protocol.

Here, when using SSTP, there may be cases when you may fail the first and second attempts. If this occurs, please click "Retry" to try reconnecting again.

When the VPN connection has been successful, the following screen will be displayed.

2. Adjusting the Connection Setting

When the SSTP VPN connection is completed by the above operations, only communications with hosts configured for VPN communication inside the University of Tsukuba campus can be made, and problems involving the inability to make Internet communications with any host will occur. Here, we recommend you adjust the connection settings with the following operations to solve this problem.

From the "Network and Sharing Center" screen, click on "Change adapter settings."

The currently defined VPN connections will be displayed. Right-click the VPN connection setting you created in the previous step and click "Properties."

When the Properties are displayed, click on the "Security" tab (with Windows XP, click on the "Network" tab). Select "Secure Socket Tunneling Protocol (SSTP)" from the "VPN Type" drop-down list.

Next, open the "Network" tab. The following screen will be displayed. Select "Internet Protocol Version 4 (TCP/IPv4)" and click on "Properties."

The IPv4 properties screen will open. Click on "Advanced settings."

The "Advanced TCP/IP Settings" screen will open. Remove the check from the "Use default gateway on remote network" check box.
If the check is left inside "Use default gateway on remote network," only communications with hosts configured for VPN communication inside the University of Tsukuba campus can be made, and Internet communications with any host will not be possible. Please always remove the check mark.

After the above settings are completed, click "OK" three times and close the properties screen.

Furthermore, if VPN connections are already established when the making the above connection settings, please disconnect the VPN connection momentarily in order to apply the setting contents.

3. VPN Connection

In order to make a VPN connection using the created SSTP VPN connection setting, click on the network icon in the bottom right of the Windows screen, and then click the VPN connections setting icon inside the displayed screen. Once the VPN connection is complete, the following will be displayed.

If the VPN connection of MS-SSTP fails

• It cannot be used in versions prior to Windows XP or OS other than Windows.
• If connections with SSTP fail repeatedly, please try using SoftEther VPN Client.
