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 service provider. Devices that cre-
ate a link from a LAN to the Internet, such as the Gigaset SX761 dsl, have a public and
a Private IP address.
PBX
Private Branch Exchange
PBX is the English acronym for a public branch exchange, which allows connection and
configuration of extensions and telephone functions.
Port
Data is exchanged between two applications in a network across a port. The port
number addresses an application within a network component. The combination of IP
address/port 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 whenever they need one.
Port forwarding
In port forwarding, the Gigaset SX761 dsl directs data packets from the Internet that are
addressed to a particular Port to the corresponding port of the appropriate network
component. This enables servers within the local network to offer services on the Inter-
net without them needing a Public IP address.

SX761 dsl, have a private and a Public IP address.
