As the name suggests, it maps one internal IP address to one external IP address. To carry out the whole process, first, it has to set up an external IP address alias, then map the inbound traffic and redirect it to the correct internal IP address. In addition, it also maps the outbound traffic from the internal IP address and directs it to the destined external IP address. Note: This section is available only when you configure the route mode as NAT on the Route Mode page. DBG-2000, the Nuclias cloud gateway, allows you to configure 1:1 NAT rules and displays all the configured 1:1 NAT rules. 87
