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
PPPoE user name and 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
PPTP connect some nodes. 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
