方法1:需要修改注册表

It’s easy to get the game to use the Hamachi adapter, which allows you to see other peoples games listed in the LAN browser but it still gives an error when you try to join the game.
Open up regedit, go to HKEY_CURRENT_USERSSoftwareClassesSoftwareMicrosoftXLive and make a new String Value named ConnectionOverride with a value of ’Hamachi’ (or whatever the name of your Hamachi adapter is). This will now cause all Live games to use Hamachi as the primary adapter (which can be confirmed by hitting Home while in game, and going down to options->network. It should tell you what network the game is currently using).

說得很明白，我就不翻譯了

把一個蓋好的reg 送給大家，看不懂的兄弟直接用我這個reg 就可以了
成效：已經能讓對方見到你建的網絡，或者看到對方建的網絡了，不會和以前一樣是：無法找到配對
個人試驗結果：但是在加入游戲的過程中，還是存在問題而退出
方法： 實際上是將 hamchi adp 設置為主網卡模式，讓live 錯誤識別，從而得到成效，，
如果哪位高手能解決這個最后的問題，GOW 的聯網方面的破解就宣告結束

方法2 （自己翻译了下）
Open your network connections. 打开网络链接
2) right click on local area connection, click disable. (you will lose your connection) 关闭网络链接（你上网用那个）
3) open GoW. create a coop game. wait for the game to load. 进入游戏，建服，等待游戏载入完毕
4) once you are in the game, tab out and enable your network connection again. 切出桌面，打开网络链接
The person who is joining your game:
1) complete steps 1 and 2 重复 1 。 2 步骤
2) open GoW. go to the coop LAN browser. let it search for a game, it should say that it cant find any. 进入游戏，刷新游戏，发现找不到任何网络
3) tab out, enable your local area connection. refresh the server browser. 切出游戏，打开网络链接
4) the game appears. 切回游戏，可以找到网络了
此方法性质和第一个方法一致，都需要进一部破解，不过已经能找到对方网络了，期待更加高手的人能破解出来
