Viewing NAT Information
Network Address Translation (NAT) is the process of modifying network address information in
datagram packet headers while in transit across a traffic routing device for remapping a given
address space into another.
Most NAT devices allow the network administrator to configure table entries for permanent use.
This feature is referred to as port forwarding, and allows traffic originating in the “outside” network
to reach designated hosts in the masqueraded network.
To view NAT information navigate to
Settings > Diagnostics > NAT
. The
NAT
page appears.
