with private IP addresses appear to have public IP addresses.
To configure one-to-one NAT, choose Firewall > Access Control > One-to-One NAT.

have been configured. It displays the following fields:

Private Range Begin—The starting IP address in the private (LAN) IP
address.
•
Public Range Begin—The starting IP address in the public (WAN) IP
address.
•
Public IP Subnet Mask—The Subnet Mask of the public IP address.

Range Length—Range length maps one to one private address to public
address up to the given range.

one-to-one NAT allows you to configure the service to be accepted by the private
IP (LAN) address when traffic is sent to the corresponding public IP address.
