IP Network Address Translation (NAT) Commands
Overview
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)
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.
