A port is an interface or connection. There are two types of ports - physical and logical.
Physical ports allow you to connect network devices. For example, your V-Portal has 4 ports
on it. One Ethernet port, an Internet port where you can connect a modem and 2 phone ports
where you can connect your telephones or fax machine.
Port
In TCP/IP networks, ports are logical connections. Every IP address is divided into ports. This
allows one IP address to be used by multiple programs to send and receive data at the same
time. Logical ports are assigned numbers that identify the type of port it is. For example, port
80 is used for HTTP traffic and port 110 is used for email.
Point to Point Protocol over Ethernet. PPPoE is a protocol for connecting users on an
Ethernet LAN to the Internet through a DSL broadband connection. In addition to data
transport, the DSL connection provides authentication through the use of a user name and
PPPoE
password that you or your ISP has selected. Your V-Portal (or your current home networking
equipment) stores this information and sends to your ISP. Your ISP then checks this
information and lets you connect to the Internet through them.
Point to Point Tunneling Protocol. PPTP is used to extend VPNs (Virtual Private Networks). A
VPN is a private network of computers that uses the Internet to connect some nodes. PPTP
PPTP
allows companies to extend their VPNs by using private "tunnels" over the Internet. PPTP is
used to ensure that messages are secure when they are transmitted through the tunnels from
one VPN to another.
Protocol
A set of rules that, when followed, allows two devices to communicate.
A computer that acts as a bridge between two other computers that use different standards,
Proxy
formats, or protocols.
A network device that lets you connect more than one piece of equipment (like computers) to
Router
your DSL or cable modem to share one Internet connection. Some ISPs supply combination
modem/routers.
Simple Mail Transfer Protocol. SMTP is a protocol used for sending and receiving email on a
SMTP
TCP/IP network.
In general, spoofing is a term used in networking to describe the ways in which software and
hardware can be fooled. An example of this would be spoofing a MAC address. Spoofing a
Spoofing
MAC address will alter the header of a packet to make it appear as if a message was sent
from an authorized computer.
A subnet mask is used determine whether traffic generated by network devices will be
Subnet
directed internally within the LAN or externally over the Internet connection based upon the
Mask
ultimate destination address (i.e. IP address) of that traffic.
Syslog is a standard for logging messages in an IP network. The term is often used to refer to
Syslog
the protocol for logging the messages as well as the file containing the messages. Syslog is
typically used for computer system management and security auditing.
Transmision Control Protocol. A protocol for transmitting data over a network, such as the
TCP
Internet, that requires the recipient of the data to acknowledge it has been received.
Traceroute is a utility used to determine the route a packet has taken from your computer,
Traceroute
across the Internet, to its specified destination.
User Datagram Protocol. UDP enables programs on networked computers to send short
UDP
messages to one another.
Universal Plug and Play. UPnP is a standard that enables devices to be plugged into a
UPnP
network and automatically know about each other.
Virtual Private Network. A VPN is a private network used to communicate over the public
VPN
Internet. It is often used by companies to connect remote sites or users together.
WAN
Wide Area Network. A WAN is a network that covers a relatively broad geographic area.
