Example 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, they do not
appear as drop-down menu options, and network objects must be created in order to represent them.
1. Select User Defined in the Source Address drop-down menu. The Edit Network Object screen appears.
Figure 68: Edit Network Object
2. Click New Entry. The Edit Item screen appears.
Figure 69: Edit Item
3. In the Network Object Type drop-down menu, select IP Address, and then enter 192.168.1.10.
4. Click OK to save the settings.
5. Click OK once more in the Edit Network Object screen.
6. Back in the Add NAT/NAPT Rule screen, in the NAT Addresses drop-down menu, select the 192.168.71.12
option. The screen refreshes, adding this address as a NAT IP address.
7. Click OK to save the settings. The NAT rule is displayed in the NAT screen.
Figure 70: NAT/NAPT Rule Sets
This rule translates one LAN IP address to one NAT IP address which means that this LAN computer will have
WAN access at all times. The status is therefore set to "Active".
Example 2: Translate the range 192.168.1.11-192.168.1.15 to 192.168.71.12-192.168.71.15
Define this NAT rule in the same manner depicted above with the exception of selecting IP Range (instead of
IP Address) as the network object type. Since neither range is predefined (and therefore not found in the
drop-down menu options), network objects must be created in order to represent them. This is done with the
User Defined option. The rule is displayed in the NAT screen.
