EA has removed the Direct IP feature for multiplayer in FIFA 11. Only LAN mode is available, this was probably to eliminate VPNs like Hamachi and Tunngle from the scene as you can’t play FIFA 11 through LAN mode on Hamachi or Tunngle.
Don’t worry another VPN called “GameRanger” has come to rescue. Yes, you can play FIFA 11 online with your friends using GameRanger without any connection losses.
Experience may become lagfest at times.
FIFA 11 LAN Online GameRanger Guide
First, you need to download and install GameRanger. Once the installation is completed, you will be prompted to register an account. Make one for yourself and it is totally free.
Search for a file named “rna.ini” in “Game” folder of your FIFA 11. If it is present then open this file with a text editor and remove everything in it and save it. Make this file as “Read Only”. If it is not present there already, then you should create a new text file and name it as “rna.ini”. File extension should be .ini and not .txt. Save it and mark the file as “Read Only”.
Now log into your GameRanger Account and create a room or join an already created room. You can make your room password protected if you want.
If you want to host a game, launch FIFA 11 and start a new game from Online Modes>Multiplayer>LAN Play. Enter your name and you will be in the game lobby. Now wait for others to join.
If you want to join the game, you need to search for the LAN games. You will be able to see the hosted games. Obviously you should be in the same room of GameRanger as the Host.
FIFA 11 supports up to 5 on 5 matches. So either you can take your rivals one on one or you can play with them with your friends. Best of Luck.
