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 (LAN) it administers.

BSSIDBasic Service Set ID

BSSID permits unique differentiation of one wireless network (WLAN) from another. In Infrastructure mode, the BSSID is the MAC address of the Access point. In wireless networks in Ad-hoc mode, 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 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.

DHCPDynamic Host Configuration Protocol

DHCP handles the automatic assignment of IP addresses to network components. It was developed because of the complexity involved in defining IP addresses in large networks

–especially the Internet – as participants frequently move, drop out or new ones join. A DHCP server automatically assigns the connected network components (DHCP Cli- ents) Dynamic IP addresses from a defined IP pool range 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 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 that are not to be run from behind the firewall for security reasons or if Internet applications 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 components remain secure behind the firewall.
