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.

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

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 SX761 dsl as a Vir-
tual server.
Network
A network is a group of devices connected in wired or wireless mode so that they can
share resources such as data and peripherals. A general distinction is made between
local networks (LANs) and wide-area networks (WANs).
Network adapter
The network adapter is the hardware device that creates the connection between a net-
work component and a local network. The connection can be wired or wireless. An Eth-
ernet network card is an example of a wired network adapter.
A network adapter has a unique address, the MAC address.
