5.3 Using NAT
(Only available in Gateway and Wireless Routing Client mode)
NAT, also known as Network Address Translation, functions by transforming the
private IP address of packets originating from hosts on your network so that they appear
to be coming from a single public IP address and by restoring the destination public IP
address to the appropriate private IP address for packets entering the private network.
The multiple PCs on your network would then appear as a single client to the WAN
interface.
Enabling NAT
Click on NAT from the CONFIGURATION menu.
By default, the NAT Status
radio button is enabled.
To change the NAT Status:
Select the appropriate radio
button.
Click on the
Apply button.
NOTE
Disabling NAT will disable Internet Sharing. Broadband Internet sharing
requires this option to be Enabled.
When NAT is enabled, your network is not accessible to the WAN. However,
implementing virtual servers allows you to host Internet servers such as Web servers,
FTP servers or Mail servers on your network, in spite of NAT.
