Run HeadlessMC with './hmc' and login to your Minecraft account with 'login [email] and password [password].
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 input these connection details in this order. (If there isnt anything for IP, use your external IP)
IP '$externalip'
Port '$openport'
Password '$pass'"
