Steps for Hosting a game:
Modern Warfare 2.
Alteriwnet latest Patch
Download Link: http://alteriw.net/viewtopic.php?f=3&t=24
And a good ISP with Ports opened. ( If you are able to host COD4 MP means leave this )
Nice GPU with 60fps+ constant.
Just Download [ DLCs Repository (961 MB) ]
and then the [ Patch 3 (small) ]
Extract the DLC Repository to the Modern Warfare Installed Directory and overwrite it if it ask..
Then the Patch 3 Small and overwrite it too if it ask..
Run alterIWnet_configure.exe and Enter your Multiplayer Tag or username tat you use to call it and save it..
Now Run iw4mp.exe and then make sure you have seen Nat opened in the game..
Now click Play, then the Private match and change the game settings to FFA ( free for all ) if you have just 1 player. and change the other setting as you wish and wait in the lobby. ( dont click Start Game )..
Now go to whatsmyip.com note down your ip and sent it to your friend via xfire or anything that u use to chat between u both..
Now your friend must use the command in the consol as ( Connect 117.193.***.** )
[ Dont use the bracket, just type connect and a space and then the IP address and press enter. ]
in the console running the background and it will straightly take you to the lobby that your other friend is hosting..
Now when he gets into lobby click start game, you will be 1st in the game with 0 players and in few seconds your friend will join the game...
Thats it guys Play some game and share your experience here..
Best way for the server to make changes soon as in the game is to in windowed mode.
to do it, go to modern warfare 2 folder and then player folder and open config_mp.cfg with note pad. Search for Fullscreen and change it from 1 to 0.
For those who will be the HOST, Pls run this app in the background before you start the game..
Select the maps and game modes and then go to console and press F7 to load the change that you have made now...
