NAT and Static NAT

The NAT and Static NAT script allows you to perform either of static 1:1 mapping, where a number of

IPs behind one interface have a 1:1 mapping to other IPs on another interface.

But the most common usage by far is to perform “masquerading”, which is to map all private IPs

behind one interface to a public IP on another interface. This anonymizes the systems on the private

network and prevents direct access to them from the outside.
