Glossary of Wired Networking Terms
NAT - Network Address Translation. This process allows all of the
computers on your home network to use one IP address. Using the NAT
capability of the Belkin 4-Port Cable/DSL Gateway Router, you can access
the Internet from any computer on your home network without having to
purchase more IP addresses from your ISP.
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.
SPI - Stateful Packet Inspection. SPI is the type of corporate-grade Internet
security provided by your Belkin 4-Port Cable/DSL Gateway Router. Using
SPI, the gateway acts as a "firewall," protecting your network from
computer hackers.
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, which must be assigned by InterNIC).

standard protocol for data transmission over the Internet.
WAN - Wide Area Network. A network that connects computers located
