**DO NOT CLOSE THIS TERMINAL UNLESS YOU ARE SURE YOU WILL NOT NEED IT**

To connect to your server, run './playit-0.9.3'. When the browser opens, click where it says 'create a guest account' and then click 'Add tunnel'. For 'Tunnel Type' choose 'Minecraft Java' then click 'Next'. Set Local IPV4 to '$internalip' and Local Port to '$openport' Click 'Next' and then 'Create Tunnel'. Click the X in the top right of the box, and keep the browser window open.

Now open another terminal, and run HeadlessMC with './launchpb' and use 'launch [id number next to the forge install] -id' to launch the Pingbypass server.

On 3arthh4ck in the multiplayer menu, turn Pingbypass ON, and click the book to edit your connection details. For Proxy-IP put the IP of the tunnel from playit.gg, and for Proxy-Port, the port from playit.gg. In the last box, put in your Pingbypass password, which is $pass.

For your reference, your Internal IP is $internalip, your Minecraft port $openport, and pingbypass password is $pass"
