Not much has changed since we first created this post almost two years ago, just updates to Hamachi and some links, but I figured that a rewrite was in order due to its popularity. Hope this helps.
- Install the free, unmanaged version of LogMeIn Hamachi². Download it here.
- Click the Power button and choose your Client name. All of your friends will be able to see this name.
- Create a new network, then choose a Network ID and Password. Entering a password here makes the Hamachi network private and you will not need a separate password for the TF2 listen server.
- Instruct your friends to follow steps 1 and 2, then Join an existing network.
- Give them the Network ID and Password so that they may join your private Hamachi network.
- Start up Team Fortress 2 and choose Create Server in the menu. In the popup window, you can enter the game server name, max number of players, and other options. Leave the Server password blank.
- Choose any map, as you will need to change it once you are on the server. Click Start.
- When loaded in, open the console with the ~ key. If nothing happens, you need to enable the console.
- Type “sv_lan 0″ and click Enter. A map change is required for this to take effect, so still in console…
- Type “map <map you and your friends want to play on>” and click Enter.
- Once the map changes, have your friends start up TF2. They can attempt to connect to your newly-created listen server by:
- opening their console and typing “connect <your Hamachi IP address>” or
- opening their console and typing “connect <your Hamachi IP address>:27015″ or
- connecting through the Steam Friends list to you or someone who has already joined.
- You can add a listenserver.cfg file to your config directory (team fortress 2\tf\cfg) and every time you create a listen server, any commands included will run, e.g. “sv_lan 0″.
- Do not put a map change command in the listenserver.cfg file: it will cause the server to continually loop and never load.
- Your online Hamachi network friends will be able to see when your PC is on if you do not Power off.
- UPDATE! As of March 25, 2012, LogMeIn has updated its non-commercial user policy for Hamachi: it is only free for up to six people. An account must be set up with a low yearly fee if you want a larger network.
