4. Back in the 'Add NAT/NAPT Rule' screen, select the '192.168.71.12' option in the
'NAT Addresses' combo box. The screen will refresh, adding this address as a
NAT IP address.
5. Click 'OK' to save the settings.
This NAT rule will be displayed in the 'NAT' screen:
Figure 8-21: NAT/NAPT Rule Sets
This rule translates one LAN IP address to one NAT IP address, meaning that this
LAN computer will have WAN access at any time. The status is therefore set to
"Active".
STEP 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 both ranges are not predefined (no such combo box options), network
objects must be created in order to represent them, using the 'User Defined' option.
The rule will be displayed in the 'NAT' screen:
Figure 8-22: 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 ac-
cess at the same time. However, note that the NAT address 192.168.71.12 is al-
ready in use by the first rule. Watson 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
therefore set to "Active".
