DSA-3110 Hotspot Edition – User Manual

NAT Function

The

NAT (Network Address Translation) service

allows using a single private IP addresses in

several internal subnets, thereby fewer registered IP addresses are required.

A NAT-enabled device is located on the edge between the public and private networks and translates
private IP addresses to unique global IP addresses before sending packets to the external network.
The NAT service can perform

static

or

dynamic

translation.

Static NAT

is a type of translation

where a user himself configures addresses in the mapping table. In this case, specific internal
addresses are mapped to previously specified external addresses.

Dynamic NAT

is a type of

translation when a NAT-enabled edge device is configured to translate internal (private) addresses to
external (public) ones taken from a previously specified address pool. As well, several internal hosts
of a network can use one external IP address, which helps to save address space.
