Configuration Description

In cases where an ISP assigns to your SmartNode’s WAN interface a public IP address, and provides you as well with multiple public IP addresses within the same subnet, all to be assigned to different hosts/servers within your network. The SmartNode being your access router, these hosts/servers will be sitting on the LAN side behind the SmartNode, and will physically be carrying private IP addresses within the local LAN subnet (example:192.168.1.100 and 192.168.1.101).

You would need these hosts/servers to be accessible from the WAN side with their secondary public IP addresses. To achieve this, a static NAPT profile needs to be configured. This configuration allows SmartNode to map between the local IP address of the host and its corresponding public IP address.
