How NAT (network address translation) is implemented

NAT (Network address Translation) Implementation method: Static NAT, dynamic Nat,napt,easy ip,napt (network address port conversion, Web addresses ports translation).

Static NAT: Static NAT implements a one-to-one mapping of private addresses and public addresses. You can use static NAT if you want a host to take precedence over an associated address, or if you want the external network to use a specified public address to access the internal server.

Dynamic NAT: Converts a private address and public address based on an address pool.

NAPT: Allows multiple internal addresses to be mapped to different ports of the same public address.

Easy IP: Allows multiple internal addresses to be mapped to different ports on the gateway outbound interface address. Easy IP is suitable for scenarios where hosts in small LANs have access to the Internet. Internal host is not many, out of the interface can be dialed to obtain a temporary public network IP address. Easy IP enables internal hosts to access the Internet using this temporary public IP address.
