Core Issue

Network Address Translation (NAT) replaces IP addresses within a packet with different IP addresses. It is useful in the following instances:


  • To conserve IP addresses
  • To connect a private network with an unregistered address to a public network such as the Internet
  • During network migration, which involves renumbering of the nodes
  • To connect networks with overlapping addresses
  • To implement Transmission Control Protocol (TCP) load distribution
  • To distribute other TCP and User Datagram Protocol (UDP) based services
