Need help understanding and configuring ip routing

[boytechnician96]

Hello wonderful people,

Since this has to do with more Internet connectivity than my Xbox, I went ahead and placed the problem here, although I am doing this mainly for my Xbox.

So when I became an owner of my Xbox a few months ago, I got deemed a strict NAT. I researched how to fix my NAT type then and had gotten it opened. However, one of the computers in the house became unable to connect to the Internet. I had realized that this computer was that odd red head stepchild because I had tried to switch our 802.11 from b to I think g; and of course the same scenario applies. I had been told by an IT tech friend of mine that I would have to go do some ip routing, and I had tried to do it previously, but it frustrated me so much, that I just had to put it back to old settings. Can someone make an explanation of how ip routing works and how I need to specifically configure it? Modem is a Netopia-3000. The computer with the problem is windows 7 os and is an emachines laptop about 3 years old.

Thanks for the help, and when you explain ip routing, explain to where the most stupidest person understands it, because I sometimes need the most interesting and dumbest analogies. Peace out awesome people

Well, to be honest. I don't think that you need to understand IP routing to get everything configured correctly. What I would do is go back to square one and set everything back the way it was in your router so that what ever happened to cause your windows 7 machine to stop working has un happened. Then in order to solve the strict nat problem with your xbox, I would look though your router's settings for something labeled DMZ. Usually a router supports adding one device or IP address to the DMZ.

The DMZ is a special area that you can put a host (in this case your xbox) to open it up to unsolicited traffic from the internet. Meaning, your xbox will be more open to the world while the rest of your network remains safer behind your NAT firewall. This should fix up your issues without doing any complicated routing that your devices probably don't support anyway.
