ISP Gateway Address:
(see ISP for definition). The ISP Gateway Address is an IP address for the
Internet router located at the ISP's office.
ISP:
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. The MAC address is a unique identifier for a device with an Ethernet
interface. It is comprised of two parts: 3 bytes of data that corresponds to the Manufacturer ID (unique for
each manufacturer), plus 3 bytes that are often used as the product’s serial number.
NAT:
Network Address Translation. This process allows all of the computers on your home network to
use one IP address. Using the On-Q Router/Switch’s NAT capability, you can access the Internet from
any computer on your home network without having to purchase more IP addresses from your ISP.
Port:
Network Clients (LAN PC) uses port numbers to distinguish one network application/protocol over
another. Below is a list of common applications and protocol/port numbers:

relies on
two widely accepted standards, Ethernet and the Point-to-Point Protocol. It is a communications protocol
for transmitting information over Ethernet between different manufacturers
Protocol:
A protocol is a set of rules for interaction agreed upon between multiple parties so that when
they interface with each other based on such a protocol, the interpretation of their behavior is well defined
and can be made objectively, without confusion or misunderstanding.
Router:
A router is an intelligent network device that forwards packets between different networks based
on network layer address information such as IP addresses.
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 (e.g. 255.255.255.0) configured like an IP address. It is used to create IP address
