IP Network Address Translation (NAT) Commands

Network Address Translation (NAT) makes use of five basic structures:

■

“public” or externally visible address ranges

■

“map” rules that bind an interior, private address range with a public address range

■

“map-lists”, which are ordered lists of maps

■

“ser vers”, which define a mapping between a private IP address and por t and a public IP address (and the 
same por t)

■

“ser ver-lists” which are lists of ser vers.

ip nat public tag dynamic from-address to-address

This command allows you to allocate a dynamic range of exterior, public addresses for use by Network Address 
Translation. This range of addresses will be associated dynamically with private addresses you will define when 
you create a map. tag is the name you assign to the range, and it can contain up to 16 characters.

The following creates a dynamic public range of 8 addresses star ting at 163.176.12.1:

ip nat public "my second range" dynamic 163.176.12.1 163.176.12.8
