Static NAT involves statically configuring one-to-one mappings of private IP addresses to public IP addresses.
An inside local IP address is mapped to an inside global IP address.
Inside Local - The IP address of the inside host, from the perspective of the local network *the IP address actually configured on the inside host, usually a private address.
Inside Global - The IP address of the inside host, from the perspective of outside hosts. *the IP address of the inside host after NAT, usually a public address.
Static NAT allows devices with private IP addresses to communicate over the Internet. However, because it requires a one-to-one IP address mapping, it doesn't help preserve IP addresses.
