Broadcast
A broadcast is a data packet not directed to a particular recipient but to all the network
components in the network. The Gigaset SX763 WLAN dsl does not pass on broadcast
packets; they always remain within the local network (
) it administers.
BSSID
Basic Service Set ID
BSSID permits unique differentiation of one wireless network (
) from another. In
. In wireless net-
, the BSSID is the MAC address of any one of the participants.
Client
A client is an application that requests a service from a
server
. For example, an HTTP cli-
ent on a PC in a local network requests data, i.e. Web pages from an HTTP server on the
. Frequently the network component (e.g. the PC) on which the client applica-
tion is running is also called a client.
DHCP
Dynamic Host Configuration Protocol
DHCP handles the automatic assignment of
to network components. It was
developed because of the complexity involved in defining IP addresses in large networks
– especially the
– as participants frequently move, drop out or new ones join.
A DHCP server automatically assigns the connected network components (DHCP
from a defined
thus saving a great deal of con-
figuration work. In addition, the address blocks can be used more effectively: Since not
all participants are on the network at the same time, the same IP address can be
assigned to different network components in succession as and when required.
The Gigaset SX763 WLAN dsl includes a DHCP server and uses it to assign automatic IP
addresses to PCs in the local network. You can specify that the IP addresses for certain
PCs are never changed.

DMZ
Demilitarised Zone
DMZ describes a part of a network that is outside the
. A DMZ is set up, as it
were, between a network you want to protect (e.g. a
) and a non-secure network
(e.g. the
). A DMZ is useful if you want to offer
services on the Internet
that are not to be run from behind the firewall for security reasons or if Internet appli-
cations do not work properly behind a firewall. A DMZ permits unrestricted access from
the Internet to only one or a few network components, while the other network com-
ponents remain secure behind the firewall.
