Device Configuration
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.
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.
10.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.
