these two protocols, contact your ISP for an authentication script.
PPP
Short for Point-to-Point Protocol, a communications protocol for transmitting
information over standard telephone lines between devices from different
manufacturers.
PPPoE
Short for PPP over Ethernet, relying on two widely accepted standards, Ethernet and
the Point-to-Point Protocol. It’s a communications protocol for transmitting information
between devices from different manufacturers over an Ethernet.
PPTP
Short for Point to Point Tunneling Protocol, PPTP encapsulates the packet for
transmission over the Internet. It is similar to creating a private “tunnel” over a large
public network and has almost equal security to a private network without actually
leasing a private line.
Protocol
An agreed format for transmitting, sending and receiving data between two devices.
Roaming
The ability for a wireless device moving from one access point’s range to another
without losing the connection.
Router
An Internet device that routes requests for information to other routers until the
information’s location is found and the data can be transmitted back to the origin of the
request.
SPI
SPI is an acronym for Stateful Packet Inspection. The SPI engine examines not just
the headers of the packet, but also the packet contents, it can then determine more
about the packet than just its source and destination information. Moreover, stateful
inspection firewalls also close off ports until a connection to the specific port is
requested.
TCP/IP
Short for Transmission Control Protocol and Internet Protocol, the suite of
communications protocols that enable hosts on the Internet to connect and exchange
streams of data.
VPN
VPN is an acronym for Virtual Private Network. Via access control and encryption,
VPN brings the same security to data transmission through the Internet as if it is being
transmitted through a private network. It not only takes advantage of economies of
scale but also ensures high level security while the packet is sent over the large public
network.
Wide Area Network (WAN)
A system of LANs being connected by telephone lines and radio waves. Although
