Call of Duty 4
How to Bridge Host
By: KDS08
First of all you are going to need Zone Alarm Pro, (you might have this from bridging Halo 2). And you are also going to need Cain and Abel.
1. Open up Zone Alarm and click "Firewall".
2. Click the "Zones" tab.
3. At the bottom right corner click "Add".
4. Click "Add IP Range".
5. Enter Xbox Live's IP Address. 65.59.234.1 - 65.59.234.255
6. Now above the IP Range click the "Zone" Set it as trusted.
7. Now enter your IP address and set it as trusted.
8. Now enter Infinity Ward's IP address: 69.60.4.143, set it to trusted.
9. Finally save changes and keep Zone Alarm open.
10. Go into a ranked lobby, ex...Team Deathmatch...etc
11. If you are the first one into the lobby you are host.
12. If not, you are not host.
13. Have fun ending games!!!
PS, you actually didn't need Cain and Abel. Sorry for the confusion.
