NAT (Network Address Translation) problems with games consoles and computers

There are a number of issues, depending on which games console, computer, or home hub version you are using, and whether you are
sharing an IP address with other users (GG-NAT)

You can tell this by looking at this diagram

If you are on CG-NAT, then you are going to have a lot of problems, as people will not be able to connect to your machine.

You will always get Strict NAT.

This problem is mentioned here Unofficial XBOX live Guide

Please see IP address translation/sharing

A lot of other issues can be overcome by making sure you manually set a static IP address to your device, via its own network settings screen, and
not relying on the home hub to do it. Then making sure that any port mapping, is done to that IP address, and not the device name.
