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.
