Configuring a Global NAT Interface
The global interface is connected to the external internetwork. IP packets arriving
at the global interface from the outside internetwork may be looked up and
translated if necessary.
To specify the global NAT interface, navigate to the appropriate IP interface
prompt (for example,
box; ethernet/2/1; ip/192.132.22.10/255.255.255.0
) and
enter:
nat
At the NAT interface prompt (for example, nat/192.132.22.10), enter:
type global
Configuration Example

NAT for dynamic address translation:
