Chapter 9 Network Address Translation (NAT)

•

One to One

: In One-to-One mode, the Device maps one local IP address to one global IP

address.

•

Many to One

: In Many-to-One mode, the Device maps multiple local IP addresses to one global

IP address.

•

Many to Many Overload

: In Many-to-Many Overload mode, the Device maps the multiple local

IP addresses to shared global IP addresses.

•

Many-to-Many No Overload

: In Many-to-Many No Overload mode, the Device maps each local

IP address to a unique global IP address.

•

Server

: This type allows you to specify inside servers of different services behind the NAT to be

accessible to the outside world.

Port numbers do NOT change for
