Internet Service Provider. An ISP is a business that provides connectivity to the Internet
for individuals and other businesses or organizations.
LAN
Local Area Network. A LAN is a group of computers and devices connected together in
a relatively small area (such as a house or an office). Your home network is considered
a LAN.
MAC Address
MAC stands for Media Access Control. A MAC address is the hardware address of a
device connected to a network.
NAT
Network Address Translation. This process allows all of the computers on your home
network to use one IP address. The NAT capability of the Device, allows you to access
the Internet from any computer on your home network without having to purchase more
IP addresses from your ISP.
Network Address Translation can be used to give multiple users access to the Internet
with a single user account, or to map the local address for an IP server(such as Web or
FTP) to a public address. This secures your network from direct attack by hackers, and
provides more flexible management by allowing you to change internal IP addresses
without affecting outside access to your network. NAT must be enabled to provide
multi-user access to the Internet or to use the Virtual Server function.
PPPoE
Point-to-Point Protocol over Ethernet. Point-to-Point Protocol is a method of secure
data transmission originally created for dial-up connections. PPPoE is for Ethernet
connections.
Subnet Mask
A subnet mask, which may be a part of the TCP/IP information provided by your ISP, is
a set of four numbers configured like an IP address. It is used to create IP address
numbers used only within a particular network (as opposed to valid IP address numbers
recognized by the Internet.
