Yes, you can. By changing Target Path in the shortcut you use to run the Multiplayer client, it is possible (and completely legit) to have multiple connections from the same household. By funnelling each client's activity through a different port, you are preventing the server from seeing three of the same connection and, more or less, becoming confused and kicking the extraneous connections.
To modify the Target Path:
1. Right-click the shortcut to your COD4 Multiplayer client, and click 'Properties...'
2. In the target box, add '+set net_port xxxxx' (without single-quotes) outside of the quotation marks after the existing filepath.
Here, xxxxx represents the port number that your client will use to connect to internet games. The standard port for COD4 Multiplayer is 28960, so just have each person on your home network input a different port for the xxxxx value. A safe range to use would probably be 28960-28970, but you could extend upwards more if need be.
Example Modified Target Paths:
"F:\Activision\Call of Duty 4 - Modern Warfare\iw3mp.exe" +set net_port 28960
"F:\Activision\Call of Duty 4 - Modern Warfare\iw3mp.exe" +set net_port 28961
"F:\Activision\Call of Duty 4 - Modern Warfare\iw3mp.exe" +set net_port 28962
etc.
Unfortuneately, unlike Halo 3 or Halo: ODST, and many other games as well, you cannot have multiple players on the same system playing Xbox Live on any of the Call of Duty games. Even if you have different gamertags, it still won't work.
