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 broadband router’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:
Application Protocol Port Number
Telnet TCP 23
FTP TCP 21
SMTP TCP 25
POP3 TCP 110
H.323 TCP 1720
SNMP UCP 161
SNMP Trap UDP 162
HTTP TCP 80
PPTP TCP 1723
PC Anywhere TCP 5631
PC Anywhere UDP 5632
PPPoE: Point-to-Point Protocol over Ethernet. Point-to-Point Protocol is a secure data transmission method originally created
for dial-up connections; PPPoE is for Ethernet connections. PPPoE 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 numbers used only within a particular
network (as opposed to valid IP address numbers recognized by the Internet, which must be assigned by InterNIC).
