Modify screen:
The screen shows the configured public interface for this NAT rule. You cannot change the
interface. To move the rule to another interface, you must delete this rule and add a new one for the
other interface.
Private Address
Specify the private network (subnet) addresses that NAT translates to and from the public address.
IP Address
Enter the private IP address in dotted decimal notation; e.g., 10.0.0.0.
Subnet Mask
Enter the subnet mask appropriate for the private IP address range. Use dotted decimal notation; the
default is 255.255.255.255. For example, to translate all private addresses in the 10. subdomain,
enter 255.0.0.0.
In the NAT Rules list, the subnet mask is shown as the number of 1s; for example, 255.255.0.0 is shown
as /16.
