Note
1. When creating a One2One NAT rule, you must set the Start External IP. The
number of the external IP addresses is the same as the number of internal IP
addresses, which is determined by the Start Internal IP and End Internal IP. For
example, if the Start Internal IP is 192.168.16.6, End Internal IP is 192.168.16.8,
and Start External IP is 200.200.200.116, then 192.168.16.6, 192.168.16.7, and
192.168.16.8 will be mapped to 200.200.200.116, 200.200.200.117, and
200.200.200.118 respectively.
2. A One2One NAT rule can contain up to 20 external/internal IP addresses.
