8.2.7.3 Adding 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:
Figure 8-20: NAT IP Addresses
1. Click the 'NAT' tab in the 'Security' management screen. The 'NAT' screen will
appear.
2. Click the 'New IP Address' link in the 'NAT IP Addresses Pool' section. The 'Edit
Item' screen will appear.
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 enter the rest of the addresses. This se-
quence 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.
7. Click 'OK' to save the settings.
8.2.7.4 Defining NAT/NAPT Rules
You can now add NAT/NAPT rules based on these IP addresses. Click the 'New
Entry' link in the 'NAT/NAPT Rule Sets' section. The 'Add NAT/NAPT Rule' screen
will appear (see Figure 8-19).
Create the following NAT/NAPT rules:
STEP 1 Translate the address 192.168.1.10 to 192.168.71.12. In this example we
assume that LAN addresses (192.168.1.X) are not yet connected, therefore do not
appear as combo box options, and network objects must be created in order to rep-
resent them.
Select 'User Defined' in the 'Source Address' combo box. The 'Edit Network Object'
screen will appear.
Click 'New Entry'. The 'Edit Item' screen will appear.
1. Select 'IP Address' in the 'Network Object Type' combo box, and enter
192.168.1.10.
2. Click 'OK' to save the settings.
3. Click 'OK' once more in the 'Edit Network Object' screen.
