Figure 74 NAT/NAPT Rule Sets
Note: Rule number 1 now maps five LAN addresses to one NAT address. L13 subtracts all previously used NAT
addresses, requested by previous rules, from the requested NAT addresses of the current rule. The requested
range of addresses does not determine how many will be available; the number of available addresses is
determined by the previous rules configuration and order. Rules will appear as "Active" even if they only have
one usable NAT address.
Example 4: Translate the address 192.168.1.5 to 192.168.71.16 to ports 1024-1050
1. Define this NAPT rule in the same manner depicted above, with the following exception:
Select the NAPT option in the Operation section drop-down menu. The screen refreshes.
