Enable nat on virgin media super hub?

Pages 12 and 16-18 in the manual do not explain any NAT functionality, it only explains how to use a MAC to setup a wireless connection+also gives a rundown of the features available on the Super Hubs' web configuration pages.There is unfortuantely NO option which allows you to change the NAT function on the VM Super Hub as it is essential for Internet access. If you are already managing to connect to the internet then your NAT (Network Address Translation) is already functioning properly (it is activated by default). NAT is necessary to translate your private LAN IP address (eg 192.168.x.x) to your public IP address which is associated with your Virgin Media account. Private addresses are not routable on the public internet and this dynamic NAT process theoretically allows many private users on the connected LAN to share the one public IP address.
