Xbox 360: How To Open Your BT Home Hub Ports!

Question

If you use a BT Home Hub and Xbox Live, you may need to open ports for a better connection, even if your NAT tests as Open. Some issues that this will fix:
Friends list Voice chat
Joining friends list games
Joining some games such as Call of Duty 3 (could not connect to all players error), or host in some games such as Gears of War. 
I suggest backing up your router's settings after you make these changes if it works for you, and maybe before you start in case you mess something up!
1. First lets reset our BT Home Hub to its factory settings:Link
2. Go into your BT Home Hub and disable UPnP
Go to http://bthomehub.home
Click on Settings
Log in with your Hubs defult Admin password.
Click on Advanced Settings.
Click on Continue to advanced settings.
Click on Applications Sharing.
Click on UPnP.
Turn UPnP off and click apply.
UPnP
Universal Plug and Play. Great Idea. Not so good in the real world. In theory, you should disable UPnP if you set up forwarding rules. The purpose of UPnP is to automatically detect the ports that need to be opened, and open them for you. Unfortunately it doesn't always do it as efficiently as you could do it yourself. On the other hand sometimes a router with forwarding rules set up seems to connect better with UPnP enabled. Toggle both ways, remember to reboot the router after any changes you make. CONCLUSION ABOUT UPnP: Disable it before the first time you ever turn on your 360. 
3. Lets make our Xbox IP address is static:
In your 360's dashboard, go to the "System" blade and select "Network Settings", and then click "Edit Settings". You're now in the "Basic Settings" screen.
Select the "IP settings" section. (later you'll also have to adjust the "DNS Settings" section right below it.). Change it from Automatic to Manual. You'll have to change all three things listed here:
IP Address
Subnet Mask
Gateway
Make the IP address about 20 numbers higher for the last three digits. For example, if your IP address is 192.168.0.101, you can use 192.168.0.121
What numbers do I use?
a) You can simpily write them down from the xboxes dashboard while you have it set to automatic.
b) You can get this info from your PC. Go to start>>Run>>cmd. Now in the DOS interface, type ipconfig. The DNS is the same number as your gateway.
When you entered all three items, click "done" and it will prompt you to do an Xbox Live test. You will fail it, but you have to test to continue (You can cancel the test before it ends).
Now hit done again and back out to the Basic Settings, and select the DNS settings section, right under the IP Settings section. Change from Automatic to Manual. You only need to enter the Primary DNS server, leave the Secondary DNS server the way it is (blank). For the DNS server, you're going to use whatever you used for the Gateway.
That's it. Now back out, do an xbox live test (otherwise it won't save) and you'll probably still get a moderate or strict NAT, or even Open. But even if it tests as open, that doesn't mean your ports are open. But it's a good sign.
