Configure NAT Prefixes

Learn how to configure local and global NAT prefixes.

A prefix is a group of one or more individual IP addresses or IP address subnets. Prefixes are a construct of NAT which help to identify traffic. They can be either global or local in scope. Global prefixes are used when traffic of interest across all sites in a network can be identified with the same set of prefixes. For example, facilities infrastructure or print services for an enterprise. Local prefixes are used when specific prefix values change by branch location. Use local prefixes to simplify creation and administration of rules. For example, a subset of IP addresses within a subnet.
