This video teaches us the procedure of speeding up gameplay by opening NAT on your XBox 360. Firstly, we will open NAT for XBox 360. We must access the setup page of the router in order to open the NAT for XBox 360. Open the command prompt and type 'ipconfig'. Note the default gateway and type it into the Internet Explorer. Put the username and password. The username is 'admin' without the quotes. Click on the administration tab in the resultant window. If the UPnP is set to 'Disable', set it to 'enable' to test the NAT. If the UPnP is set to 'Enable' or the NAT is still not open, set it to 'Disable'. If setting UPnP to 'Enable' opened NAT you are finished. Click on 'Applications and Gaming' and 'DMZ' sub tab. Set DMZ to enable. Set 'DMZ Host IP Address' to a set static IP address for XBox Live. Click on 'Set Up' and select MTU to manual. Set size to '1364'. This finishes the procedure.
