Hello Richstar*, And Welcome to GeeksToGo. I'm Oblivionon360 and I will offer advice to the best of my knowledge.
Ok, First you will need to create a static IP. For this you will need to know the router Default Gateway IP. Go to the start menu and type command in the box. Then right-click on Command Prompt and click Run as administrator. If a User Account Control window pops up, click Continue. Then at the C;/ command prompt Type ipconfig /all Look for the information next to Default Gateway. Write this down or type it in a Notepad document. Also take note of the DNS Servers.
Next from this information you will need to determine what IP you would like to set your Xbox up with. It will need to be similar to your Default Gateway while not exact. So, If your Default Gateway is 192.168.1.1 I would suggest Something like 192.168.1.35 or 192.168.1.73. It really does not matter as long as you only change the last set of digits and do not exceed 192.168.1.254. I do suggest not using 1-10 for those are the IP's that any computer set up to automatically find an IP will use. Once you have decided this you should follow step by step Instructions for configuring your Xbox for a Static IP, found http://www.portforwa...cip-xbox360.htm
Next you will need to open ports on your router for the specific Static IP you have chosen. For this you will need to enter HTTP:// into your web browser address bar followed by the Default Gateway you found earlier. So, if your Default Gateway IP was 192.168.1.1 then your entry into the address bar should read HTTP://192.168.1.1
For the rest of the instructions you should follow a step by step guide found http://www.portforwa...ox_Live_360.htm
Unfortunately enough I could not find an accurate Guide for this particular router. The guide given in this paragraph is one that is close to what yous would be and I believe with patience you can use the guide to help you through your own router ports. If you find that the user name and password for your router provided in the guide are not accurate then you may need to do a search for a default password for a Belkin F5d7234.
If you have any other questions or comment please feel free to post them here i am usually easy enough to get in contact with.
