Figure 61: Add NAT Rule
NAT Addresses The NAT address into which the original IP address will be translated. The drop-down menu
displays all of your available NAT addresses/ranges from which you can select an entry.
Figure 62: Add NAPT Rule
NAPT Address The NAPT address into which the original IP address will be translated. The drop-down menu
displays all of your available NAPT addresses/ranges from which you can select an entry. Note, however, that
in this case the network object may only be an IP address since NAPT is port-specific.
NAPT Ports Specify the port(s) of the IP address to which the original IP address will be translated. Enter a
single port or select Range in the drop-down menu. The screen refreshes, enabling you to enter a range of
ports.

8. Logging section allows you to monitor the rule.
Log Packets Matched by This Rule Select this check box to log the first packet from a connection that was
matched by this rule.
9. Schedule By default, the rule will always be active. However, you can configure scheduler rules by selecting
User Defined, in order to define time segments during which the rule may be active. Once a scheduler rule(s)
is defined, the Schedule drop-down menu will allow you to choose between the available rules.
3.7.1.8.1 Using NAT/NAPT
This section demonstrates the NAT/NAPT usage and capabilities by creating several rules and observing their
implementation.
 To Add NAT/NAPT IP Addresses
In the following examples, LAN IP addresses are marked 192.168.1.X, while NAT addresses are marked
192.168.71.X. Assuming your obtained public IP addresses are 192.168.71.12 through 192.168.71.20, add them as
NAT IP addresses to the WAN Ethernet settings, as follows:
