Client
A client is an application that requests a service from a server. For example, an HTTP
client on a PC in a local network requests data, i.e. Web pages, from an HTTP server
on the Internet. Frequently the network component (e.g. the PC) on which the client
application is running is also called a client.
Connect on demand
Connect on demand means that applications such as a Web browser, Messenger and E-
mail automatically open an Internet connection when they are launched. This can lead
to high charges if you are not using a Flat rate. This function can be deactivated at the
Gigaset SE366 WLAN to save call charges.
DHCP
Dynamic Host Configuration Protocol
DHCP handles the automatic assignment of IP addresses to network components. It was
developed due to the fact that in large networks – especially the Internet – defining
IP addresses is very complex as participants frequently move, drop out or new ones join.
A DHCP server automatically assigns the connected network components
(DHCP Clients) Dynamic IP addresses from a defined IP pool range, thus saving a great
deal of configuration work. In addition, it also allows address blocks to be used more
effectively: Since not all participants are in 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 SE366 WLAN includes a DHCP server and can automatically assign
IP addresses to PCs in the local network. You can specify that the IP addresses for certain
PCs are never changed.

DMZ
Demilitarized Zone, see also Exposed Host
DMZ describes a part of a network that is outside the Firewall. A DMZ is set up, as it
were, between a network you want to protect (e.g. a LAN) and a non-secure network
(e.g. the Internet). A DMZ is useful if you want to offer Server services on the Internet
which, for security reasons, will not run behind the firewall, or if Internet applications
do not function correctly behind a firewall. A DMZ permits unrestricted access from the
Internet to only one or a few network components, while the other network compo-
nents remain secure behind the firewall.
