Glossary
Connection
: A link between machines, applications,
processes, and so on that can be logical, physical, or
both.
DMZ, Demilitarized Zone
: Used to host Internet
services without allowing unauthorized access to an
internal (private) network. Typically, the DMZ contains
servers accessible to Internet traffic, such as Web
(HTTP) servers, FTP servers, SMTP (email) servers
and DNS servers.
DMZ interface
: The FortiGate interface that is
connected to a DMZ network.
DNS, Domain Name Service
: A service that converts
symbolic node names to IP addresses.
Ethernet
: A local-area network (LAN) architecture that
uses a bus or star topology and supports data transfer
rates of 10 Mbps. Ethernet is one of the most widely
implemented LAN standards. A newer version of
Ethernet, called 100 Base-T (or Fast Ethernet),
supports data transfer rates of 100 Mbps. And the
newest version, Gigabit Ethernet, supports data rates
of 1 gigabit (1,000 megabits) per second.
External interface
: The FortiGate interface that is
connected to the Internet. For the FortiGate-60 the
external interface is WAN1 or WAN2.
FTP, File transfer Protocol
: An application and TCP/
IP protocol used to upload or download files.
Gateway
: A combination of hardware and software that
links different networks. Gateways between TCP/IP
networks, for example, can link different subnetworks.
HTTP, Hyper Text Transfer Protocol
: The protocol
used by the World Wide Web. HTTP defines how
messages are formatted and transmitted, and what
actions Web servers and browsers should take in
response to various commands.
HTTPS
: The SSL protocol for transmitting private
documents over the Internet using a Web browser.
Internal interface
: The FortiGate interface that is
connected to an internal (private) network.
Internet
: A collection of networks connected together
that span the entire globe using the NFSNET as their
backbone. As a generic term, it refers to any collection
of interdependent networks.
ICMP, Internet Control Message Protocol
: Part of the
Internet Protocol (IP) that allows for the generation of
error messages, test packets, and information
messages relating to IP. This is the protocol used by
the ping function when sending ICMP Echo Requests
to a network host.
IKE, Internet Key Exchange
: A method of
automatically exchanging authentication and
encryption keys between two secure servers.
IMAP, Internet Message Access Protocol
: An
Internet email protocol that allows access to your email
from any IMAP compatible browser. With IMAP, your
mail resides on the server.
IP, Internet Protocol
: The component of TCP/IP that
handles routing.
IP Address
: An identifier for a computer or device on a
TCP/IP network. An IP address is a 32-bit numeric
address written as four numbers separated by periods.
Each number can be zero to 255.
L2TP, Layer Two (2) Tunneling Protocol
: An
extension to the PPTP protocol that enables ISPs to
operate Virtual Private Networks (VPNs). L2TP merges
PPTP from Microsoft and L2F from Cisco Systems. To
create an L2TP VPN, your ISP’s routers must support
L2TP.
IPSec, Internet Protocol Security
: A set of protocols
that support secure exchange of packets at the IP
layer. IPSec is most often used to support VPNs.
