Xbox live I have 3 computers and 2 xboxs set up on my router. In order for xbox live to function properly you need to open ports 88, 2074 and 3074. Ive assigned a specific ip to my xbox and opened those ports. Ive also assigned another ip to my 2nd xbox but it seems that I can only open these ports for 1 ip. When I try to open them for the other it says "Entry containing one or more of the requested ports already exists" Is there any way around this? any suggestions?

• Port 88 (UDP)
• Port 3074 (UDP and TCP)
• Port 53 (UDP and TCP)
• Port 80 (TCP)

1. • 1 Connect only your Xbox and computer to the Internet. Disconnect all other devices. This is done to easily determine the Xbox's IP address, which is used in the Port Forwarding process.
     
   • 2 Open the Windows Command Prompt from the Start Menu. Click "Start > Run...," then type in "cmd" and hit "OK."
     
   • 3 Enter "ipconfig" n the command prompt. A list of IP addresses pop ups. Write down the IP address of your computer.
     
   • 4 Open your router setup utility through a web browser. Use the given directions from your router manufacturer to do so. Generally, the configuration page is opened by inputting the router IP address into the URL in the following format: http://123.456.7.8/ (where the IP Address number is unique to the router manufacturer).
     
   • 5 Open the "DCHP Client List" section of the router setup utility. This lists the devices currently connected to the Internet through the router, which is your computer and Xbox. Write down your Xbox's IP address (in this case, the one that is not your computer's IP address).
     
   • 6 Navigate to the "Virtual Servers" or "Port Forwarding" menu in your router setup utility. Most manufacturers have a side menu on their router setup utility, which is generally a section under your "Firewall" settings.
     
   • 7 Input the following port numbers and your Xbox's IP address into your router's port forwarding configuration:
     TCP 80
     UDP 88
     UDP 3074
     TCP 3074
     UDP 53
     TCP 53
     Placing these numbers in the port forwarding menu opens up the required ports that your Xbox needs to connect to the Xbox LIVE network. Save this configuration.
     
   • 8 Start up Xbox LIVE to check your connection. If you have no problem connecting, then you have successfully forwarded the required ports.
     

Once you have all the wireless settings of the router, you are ready to connect the play station or the x-box to the wireless network.

X-BOX

On the x-box you will need to connect to the wireless network now.
Open the main Interface of the X-Box.

1. In the Xbox Dashboard, go to My Xbox and open System Settings.

2. Select Network Settings, Configure Network.

3. On the Basic Settings tab, select your wireless settings.

4. Select the name (SSID) of your wireless network. If your router isn't broadcasting your network's name, select Specify Unlisted Network and enter the name.

5. If your network has wireless security, enter your WEP or WPA key.

6. Try to connect to Xbox LIVE again.

You can try to reduce the MTU settings on the router. if the MTU on the router is set to 1500 then change the MTU to 1365. Also you will need to open the ports on the router.

For X-box port numbers are - 53, 80-88, 3074 .
