NETWORK ADDRESS TRANSLATION (NAT)

Network Address Translation (NAT) enables the users to utilize the Private IP subnet specified by RFC1597 while still allowing the clients or servers in this network to access or to be accessed by the global Internet. It uses a mechanism that substitutes the source private IP address with a public IP address when a packet leaves the private network, and restores the destination public IP address with the private IP address when the packet enters the private network. By default, NAT is enabled. To disable NAT, click on the Disable radio button and press the Apply Button.


Disabling Network Address Translation (NAT) will disable Internet Sharing. Broadband Internet sharing requires this option to be enabled.
