Network Address Translation
NAT is a method for implementing IP addresses (mostly
) in a
network on one or more

. With NAT several network
components in a
can share the router's public IP address to connect to the Internet.
The network components of the local network are hidden behind the router's IP address
registered on the Internet. As a result of this security function NAT is frequently used as
part of the network
. If you want to make services on a PC in the local network
available on the Internet despite NAT, you can configure the Gigaset Router as a

A network is a group of devices connected in wired or wireless mode so that they can
share resources such as files and peripherals. A general distinction is made between
local networks (

The network adapter is the hardware device that realises the connection of a network
component to a local network. The connection can be wired or wireless. A wired
network adapter is for example an Ethernet network card. Wireless network adapters are
for example the Gigaset USB Adapter 11 and the Gigaset PC Card 11.

addresses an application within a network component. The combination

number uniquely identifies the recipient or sender of a data packet within a network.
Some applications (e. g. Internet services such as HTTP or FTP) work with fixed port
numbers, others are allocated a free port number every time they need one.
