You will only have to follow these steps once, when you first join!

  2. Create a installation by clicking "New".

  3. Give the new installation a name (for example “Imperial Virtual World”), and from the version drop-down menu select “release 1.15.2”. Leave everything else unchanged and press “Create”.

  4. You should now see your new installation in the list. Press the “Play” button in the top menu to return to the main screen.

  5. Select the installation that you just created from the drop-up menu and click “Play”. Minecraft will open. Make sure that before you enter the game you are connected to the Imperial VPN as instructed in the steps above.

  6. Select "Multiplayer" then select "Add Server".

  7. Input a server name of your choice and the IP address and port of the world that you wish to join. Press “Done”.

  8. Double-click on the server that you just added. You will now enter the Imperial College Virtual World, enjoy!


VPN - Warning message

In some cases, you might see the following message after you connect to the VPN.

This message DOES NOT indicate that the VPN connection is unsuccessful, it just warns you that your public IP address has not changed. This is to be expected, but you will still have access to the College’s services that require the VPN, such as the Minecraft server.

You can either ignore this message, or hide it forever. To hide it, follow the steps below:

  1. From the menu bar, click the Tunnelblick icon and select “VPN Details...”

  2. Select the “ic” configuration in the left panel, and click on “Settings” in the main section. Make sure that the “Check if the apparent public IP address changed after connecting” checkbox is UNCHECKED.

  3. Quit Tunnelblick and reopen it. You should no longer see the warning the next time you connect to the VPN.
