3.7.3.8.1 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:
1. Click the NAT link of the Firewall menu item under the Services tab. The NAT screen appears (see Figure 80).
2. Click the New IP Address link in the NAT IP Addresses Pool section. The Edit Item screen appears (see Figure
86).
3. Select the IP address option and enter 192.168.71.12.

4. Click OK to save the settings.
5. Click the New IP Address link again to add an additional Public IP to NAT IP Addresses Pool. This sequence is
for demonstration purposes; you may enter your public IP addresses in the method that suits you.
6. Select the IP range option and enter 192.168.71.13 through 192.168.71.20.
