Play Left 4 Dead 2 LAN Over Internet
The Problem
Left 4 Dead 2's Steam matchmaking can be unreliable, and hosting a local server requires port forwarding. Many players want to play with specific friends without dealing with random matchmaking or network configuration.
The Solution
MoleTun puts everyone on a virtual LAN, letting you host a local L4D2 server that friends can join directly—just like a real LAN party, but over the internet.
Setup Guide

Get MoleTun for Windows, macOS, or Linux. Quick installation.
Create a Room

Friends Join
Friends enter your code in MoleTun. Everyone's now on the same virtual network.
Host a Local Server
In L4D2, open console (~) and type: map c1m1_hotel (or any campaign map). This starts a local server.
