Glossary
LAN
Local network
A local area network (or local network) links network components so that they can
exchange data and share resources. The physical range is restricted to a particular area
(a site). As a rule the users and operators are identical. A local network can be connected
to other local networks or to a wide-area network (WAN) such as the Internet.
With the Gigaset SX763 WLAN dsl you can set up a wired local Ethernet network and a
wireless IEEE 802.11g standard network (WLAN).
Local IP address
See Private IP address
MAC address
Media Access Control
The MAC address is used for the globally unique identification of a Network adapters. It
comprises six parts (hexadecimal numbers), e.g. 00-90-96-34-00-1A. The MAC address
is assigned by the network adapter manufacturer and should not be changed.
Mbps
Million bits per second
Specification of the transfer speed in a network.
MER
MAC Encapsulated Routing
MRU
Maximum Receive Unit
The MRU defines the maximum user data volume within a data packet.
MTU
Maximum Transmission Unit
The MTU defines the maximum length of a data packet that can be carried over the net-
work at any one time.
NAT
Network Address Translation
NAT is a method for converting IP addresses (Private IP addresses) within a network into
one or several Public IP addresses on the Internet. With NAT, several network compo-
nents in a LAN can share the router's public IP address to connect to the Internet. The
network components of the local network are hidden behind the router's IP address reg-
istered on the Internet. Because of this security function, NAT is frequently used as part
of the Firewall of a network. If you want to make services on a PC in the local network
available on the Internet despite NAT, you can configure the Gigaset SX763 WLAN dsl as
a Virtual server.
