10. To map a source IP address from an internal network to a NAT IP address click the + Add Row button. Enter the
internal network IP address in Source IP field. Enter the NAT IP address in the NAT IP field.
11. Use the Network drop-down menu to set the NAT type either Inside or Outside. Select Inside to create a
permanent, one-to-one mapping between an address on an internal network and a perimeter or external network.
To share a Web server on a perimeter interface with the Internet, use static address translation to map the actual
address to a registered IP address. Static address translation hides the actual address of the server from users on
insecure interfaces. Casual access by unauthorized users becomes much more difficult. Static NAT requires a
dedicated address on the outside network for each host. Inside NAT is the default setting.
12. Select the Destination tab to view destination NAT configurations and define packets passing through the NAT
on the way back to the LAN are searched against to the records kept by the NAT engine. The destination IP address
is changed back to the specific internal private class IP address to reach the LAN over the network.
