Those who like to play the originalLeft 4 Deadwith their friends locally, ergo without an Internetconnection, may also want to play the sequelLeft 4 Dead 2on a local area network (LAN) as well. I"ve created a guide on how to host and join a local game session without relying on Steam or any other onlinegame matchmakers.

Almost two years have passed since I created this guide and a lot of game updates have been pushed through by Valve since then. As a possible fix to recent multiplayer connection problems, create a shortcut for Left 4 Dead 2.Open the shortcut’s properties, proceed to Shortcut tab and add the following at the end of the Target field:–insecure. Click Apply/OK to save the new setting.

Every time you run Left 4 Dead 2, you should do so by using this modified shortcut.The guide below will not work if you don’t use the shortcut.After following the steps above, run the game. You will then need to enable the developer console. Optionally, you can also enable automatic detection of LAN games for convenience to those who will join your hosted game. Here"s how:How to enable Developer Console:
1. At the game main menu, clickOptions.2. ClickKeyboard/Mouse.3. ClickAllow Developer Consoleand selectEnabled.

How to automatically detect LAN games:
1. At the game main menu, clickOptions.2. ClickMultiplayer.3.

Determining the host"s IP address:
Determining your local IP address can be tricky when you"re connectedto the Internet, so it"s best to stay offline when hosting a game. Anyway, the game host must typenet_statusin the developer console. Some data will appear afterwards. You will need to look for a phrase similar to this:"Net status for host 11.111.11.11:"The numbers that appear on that phrase is the host"s IP address.Other notes and info:This offline LAN game guide does not require Hamachi, Garena, or Steam. However, I suppose the version of the game installedon all computers must be the same.Make sure Left 4 Dead 2 is added to the firewall exemption.sv_allow_lobby_connect_onlyIf set, players may only join this server from matchmaking lobby, and may not connect directly.sv_lan ( def. "0" )If set, server is a lan server ( no heartbeat, no authentication, no non-class C addresses).Left 4 Dead Play on LAN (Offline)Source

if you failed to connect after 10 retries, try disable your firewall or make your dns automatic..

A misprint in 'exception'>> Make sure Left 4 Dead 2 is added to the firewall exemption.

Though they could never beat Capcom's Resident Evil Series, Valve corporation did gave them some competition with their Left 4 Dead and Left 4 Dead 2 for sure. The first installment of this franchise was really awesome.Thank you for your hard work... All the best!

Works great! We have 3 licenses in the family and a crappy internet connection...it's easier for 3 of us to connect locally to have a lag free game this way!

Can anyone please guide me on how to play addon campaigns with my friends on lan/ host an addon campaign cause there's no console command to launch an addon campaign of course, and also when I try to change the current campaign the "Addon Campaigns" option is blurred, I can't select it. I've seen many online non steam servers that are hosting addon campaigns too. Idk how to? Help would be highly appreciated.

March 23, 2017 at 9:35 AMUnknownsaid...

I'm super late but you would type the map name into the console like so: "map (map name here) campaign"

Remove -insecure from the launch options. It prevents you from joining servers.

September 30, 2018 at 5:18 AMUnknownsaid...

Remove -insecure, your plugins don't work on a server that isn't yours.
