71
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.
Figure 93: NAT/NAPT Rule Sets
This rule translates five new LAN IP addresses to four NAT IP addresses, which would normally mean that only
four of the five LAN computers may have WAN access at the same time. However, note that the NAT address
192.168.71.12 is already in use by the first rule. The W40 will therefore allow these five LAN computers to
use only the three remaining IP addresses: 71.13, 71.14 and 71.15. The status is set to "Active".
Example 3: Translate the range 192.168.1.21-192.168.1.25 to 192.168.71.13-192.168.71.14
