Configuration: Basic
A type of firewall that tracks each connection traversing all firewall interfaces to ensure validity. In
addition to examining the source and destination in the packet header based on static rules, a
stateful inspection firewall:
• Examines packet headers on context established by previous packets that traversed the firewall
• Monitors the connection state and saves it in a table
• Closes ports until a connection to a specific port is requested
• May examine the packet contents up through the application layer to determine more than just the
source and destination
A stateful-inspection firewall is more advanced than a static filter firewall.
A type of firewall that examines the source and destination in the packet header based on
administrator-defined rules only.
assigned manually. The opposite of dynamic IP address.
A bit mask that is logically ANDed with the destination IP address of a packet to determine the
network address. A router routes packets using the network address.
A part of a network; commonly abbreviated "subnet." When subnetting is used, the host portion of
the IP address is divided into a subnet and host number. Hosts and routers use the subnet mask to
identify the bits used for the network and subnet number.
Transmission Control Protocol provides reliable transport over the network for data transmitted using
IP. It defines rules and procedures for data exchange.
The Transmission Control Protocol/Internet Protocol is a set of protocols that provides rules for
communication between networks. It is the worldwide internetworking standard and the basic
communications protocol of the Internet.
Trivial File Transfer Protocol is a very simple protocol used to transfer files.
Universal Plug and Play protocol.
A uninterruptible power supply provides battery back-up for a specified time during a power outage.
In a cable data or DSL network, the direction of data sent from your computer to the Internet.
Universal Serial Bus
A device that provides network connectivity to one or more client computers using radio signals over
a wireless connection. One example you could use with your residential gateway is the
Wireless Access Point WA840G.
Voice over Internet Protocol is a method to exchange voice, fax, and other information over the
Internet. Voice and fax have traditionally been carried over telephone lines using a dedicated circuit
for each line. VoIP enables calls to travel as discrete data on shared lines.
The company from which you purchase VoIP telephone service.
A virtual private network is a private network that uses "virtual" connections (tunnels) routed over a
public network (usually the Internet) to provide a secure and fast connection, usually to users
working remotely at home or in small branch offices. A VPN connection provides security and
performance similar to a dedicated link (for example, a leased line), but at much lower cost.
A wide-area network provides a connection over a large geographic area, such as a country or the
whole world. The bandwidth depends on need and cost, but is usually much lower than for a LAN.
For the residential gateway, "WAN" refers to the VoIP and broadband provider networks.
