Multiplayer config for Farming simulator 2013 on D-Link router.

For playing farming simulator multiplayer, you first need to portforward a specific port of your router. Port forwarding is very simple. Just follow the steps below.

1. First of all, find your computers IP address (Assume this computer is creating the game and others join the game)
2. To find IP address of your computer, open command prompt and enter the command 'ipconfig'. There, against Ipv4 address you find your computer's IP address.
3. Login to your router (Enter 192.168.1.1 into your address bar. Default username and password both are 'admin')
4. It's now the actual port-forwarding procedure begins.
5. Once you're logged in, to the left of the screen you can see different options.
6. Click the Advanced Setup link.
7. You should now see a new menu. In this new menu, click NAT.
8. You should now see a new menu. In this new menu, click Virtual Servers.
9. Click the Add button near the center of the page.
10. Select custom service and give it any name.
11. Enter the server IP address as your computer's IP address which you just found before.
12. Below, there are 4 text fields where we enter the port number which we want to forward. Enter 10823 in 4 of those fields and choose the protocol as TCP/UDP
13. Now, it should look something like this.

External Port Start   External Port End   Protocol   Internal Port Start   Internal Port End

                             TCP/UDP                       

  14.   Now click apply/save. Port forwarding is done!

  15.   Now open the game, choose multiplayer and create game. The other players can join the           game by clicking join game in multiplayer.

  16.   Done! :)
