-======How to Host NFS Underground Without a Public IPv4 (Using a VPS Relay)====== +====== How to Set Up a VPN to Host NFSU ====== 
-==== This tutorial has not been tested. Use it with caution, and if anyone notices a mistake, please feel free to correct it. ====+  - Get the cheapest VPS you can find with a dedicated IPv4 address. 
 +  - Select the latest Debian as the server image. 
 +  - On a freshly installed server, log in via SSH and run the following command: <code>wget -O - https://nfs.onl/pivpn | bash</code> 
 +  - At the end of the script, open the shown URL in a web browser and download the .conf file. 
 +  - Install the WireGuard client from https://www.wireguard.com/install/ 
 +  - Open the WireGuard app. 
 +  - Import the .conf file and click "Activate".
  
-Some players today cannot host old games like NFS Underground directly because their home connection lacks a public IPv4 address.\\ +Done.
-However, you can still host by using a VPS (Virtual Private Server) as a relay. This guide explains step-by-step how to do it on a Linux VPS Server.+
  
-**Estimated Setup Time:** ~25–40 minutes.+Here you can see how it looks: {{youtube>ScveKTwyuV0?large}} 
 +As long as you are connected to your VPN, you will be able to host games on an NFSU server.
  
-==== Step 1 - Rent a VPS ==== +Here’s what the fully automated script does: 
-- Get a small Linux VPS with a **dedicated IPv4** (~€1-3/month)\\ +  - Installs PiVPN with a WireGuard server 
-- Make sure you have SSH access +  - Creates a configuration for the WireGuard client 
- +  - Sets up port forwarding for UDP 3658–3659 
-==== Step 2 - Install Relay Software ==== +  - Opens the necessary ports in the firewall 
-*Open a terminal on your VPS and run:* +  - Runs a temporary web server so you can download the config file to your PC 
- +  - Saves the firewall settings to make them persistent
-sudo apt update +
-sudo apt install socat screen -y +
-# socat will forward the game ports from the VPS to your PC +
- +
-==== Step 3 - Prepare Your PC ==== +
-- Assign a **static LAN IP** (e.g., 192.168.1.100)\\ +
-- This ensures the VPS always knows where to send game data\\ +
-- Make sure your firewall allows UDP ports 3658–3659 (NFS Underground default) +
- +
-==== Step 4 - Set Up Port Forwarding on the VPS ==== +
-*Run these commands in the VPS terminal to forward UDP ports to your PC:* +
- +
-socat UDP4-RECVFROM:3658,fork UDP4-SENDTO:192.168.1.100:3658 & +
-socat UDP4-RECVFROM:3659,fork UDP4-SENDTO:192.168.1.100:3659 & +
- +
-==== Step 5 - Keep the Relay Running ==== +
-*Use screen or tmux in the VPS terminal to keep socat running:* +
- +
-screen -S nfsrelay +
-# run socat commands here +
-# detach with Ctrl+A, D +
- +
-- Optionally, configure socat as a systemd service to start automatically on VPS boot +
- +
-==== Step 6 - Open VPS Firewall ==== +
-*Run these commands in the VPS terminal:* +
- +
-sudo ufw allow 3658/udp +
-sudo ufw allow 3659/udp +
-sudo ufw enable +
-# only open necessary ports for security +
- +
-==== Step 7 - Start Hosting ==== +
-- Launch NFS Underground on your PC\\ +
-- The game registers in the lobby automatically\\ +
-- Players connect using the VPS public IP, but the game actually runs on your PC\\ +
-- No extra software is needed for players +
- +
-==== Tips ==== +
-- Test first with 1-2 friends to make sure everything works\\ +
-- Ensure your PC has a static LAN IP\\ +
-- Only forward necessary UDP ports (3658-3659)\\ +
-- Multiple VPS relays can be set up if needed+
