LAN
Locan Area Network (LAN) connects computers and peripherals together in
an office or a campus to allow the computers to access each other and other
common peripherals.
LEDs
Abbreviation of light emitting diode, an electronic device that lights up when
electricity is passed through it. LEDs are usually red, but the ANG-1000 uses
green LEDs. The LEDs are used to indicators.
Mac Address
Short for Media Access Control address, a hardware address that uniquely
identifies each node on a network.
Network Address Translation (NAT)
Described by Whatis.com as the translation of an Internet Protocol address
used within one network to a different IP address known within another
network. One network is designated the inside network and the other is the
outside. Typically, a company maps its local inside network addresses to one
or more global outside IP addresses and unmaps the global IP addresses on
incoming packets back into local IP addresses. This provides security since
each outgoing or incoming request must undergo a translation process that
also offers the chance to qualify or authenticate the request or match it with a
previous request. NAT also conserves the number of global IP addresses that
a company uses and permits the use of a single IP address to interface with
the world. RiverMaster permits the Aurorean Network
Gateway to
be configured as a NAT server.
