Port Forwarding
In port forwarding the Gigaset SE551 WLAN dsl/cable directs data packets from the

Internet

that are addressed to a particular

Port

to the corresponding port of the appro-

priate network component. This enables servers within the local area network to offer
services on the Internet without them needing a

Public IP address

.

Private IP address
The private

IP address

(also known as the local IP address) is a network component's

address within the local area network (

LAN

). The network operator can assign any

address he or she wants. Devices that act as a link from a local network, such as the
Gigaset SE551 WLAN dsl/cable, have a private and a

Public IP address

.

Protocol
A protocol describes the agreements for communicating on a network. It contains rules
for opening, administering and closing a connection, as well as about data formats,
time frames and handling possible errors. Communications between two applications
require different protocols at various levels, e.g. the

TCP/IP

protocols for the

Internet

.

Public IP address
The public

IP address

(also known as the global IP address) is a network component's

address on the

Internet

. It is assigned by the

Internet Provider

. Devices that create a link

from a LAN to the Internet, such as the Gigaset SE551 WLAN dsl/cable, have a public and
a

Private IP address

.

Rekey Interval
The rekey interval is the period after which new keys are automatically generated for
data encryption with

WPA-PSK

.

LAN

).
