Install sudo if you haven't yet

sudo -V || apt -y install sudo

Update the Package Index

sudo apt -y update

Install curl if you haven't yet

sudo apt -y install curl

Setup IP address environment variables

# This proxy server IP address (Auto fetch)
export INSTANCE_IPV4=$(curl -4fsSL ip.denpa.io)

# The port you want to expose to your players, usually same as your Minecraft server
export EXPOSED_PORT=25565

# Your Minecraft server IP address
export BACKEND_HOST=1.2.3.4:25577

Allow Minecraft port on firewall

sudo ufw allow ${EXPOSED_PORT} 2>/dev/null || echo "ufw not found, ignore it."

Enable Google BBR
