Inline Static Destination NAT Overview


Inline static destination NAT uses the capabilities of the MPC line card to perform address translation, eliminating the need for a services card.

Static destination NAT translates the IPv4 destination address of an incoming packet to the IPv4 address of a private server. This redirects traffic destined to a virtual host (identified by the original destination IP address) to the real host (identified by the translated destination IP address).

Static destination NAT uses a one-to-one mapping between the original address and the translated address; the mapping is configured statically.


  • Allows external traffic to communicate with a private host without revealing the host’s private IP address

  • Does not require port mapping

  • Eliminates the need for a services card

  • Supports more NAT flows than a services card
