Network Address Port Translation

Network Address Port Translation (NAPT) allows multiple clients in a local network

to simultaneously access remote networks using a single IP address. This benefits

telecommuters and SOHO (Small Office/Home Office) users that have multiple

clients in an office running TCP/UDP applications. NAPT is sometimes referred to

as PAT (Port Address Translation).

NAPT provides a many-to-one mapping and uses one public address to interface

numerous private users to an external network. All hosts on the global side view all

hosts on the local side as one Internet host. The local hosts continue to use their

corporate or private addresses. When the hosts are communicating with each

other, the translation is based on the IP address and the IP port numbers used by

TCP/IP applications. Only TCP/UDP applications can access the public network.

NAPT Configuration Example

In this NAPT example the router is configured for NAPT using:

A single public IP address. Multiple public addresses can be used.

A public network. NAPT can also be used between private networks.

An access list. A pool can also be used, instead or in addition.
