What is NAT interface?

Network address translation (NAT) is a method of mapping an IP address space into another by modifying network address information in the IP header of packets while they are in transit across a traffic routing device. One Internet-routable IP address of a NAT gateway can be used for an entire private network.

Is NAT enabled by default?

Default Inbound NAT Configuration By default, nothing is allowed in from the Internet on the WAN interface. If traffic initiated on the Internet must be allowed to reach a host on the internal network, port forwards or 1:1 NAT are required.
