4.1
Basic Overview
This section describes some of the concepts related to the
Basic
screens.
4.1.1
WAN and LAN
A Local Area Network (LAN) is a network of computers and other devices that usually
occupies a small physical area (a single building, for example). Your CGN3’s LAN
consists of all the computers and other networking devices connected to the
LAN 1
~
4
ports. This is your private network (in routing mode - see
Routing Mode
on page
38
).
The LAN is a separate network from the Wide Area Network (WAN). In the case of
the CGN3, the WAN refers to all computers and other devices available on the cable
connection.

Hitron CGN3 User’s Guide
By default, computers on the WAN cannot identify individual computers on the LAN;
they can see only the CGN3. The CGN3 handles routing to and from individual
computers on the LAN.
4.1.2
LAN IP Addresses and Subnets
IP addresses on the LAN are controlled either by the CGN3’s built-in DHCP server
(see
LAN Settings
on page
28
), or by you (when you manually assign IP addresses to
your computers).
For more information about IP addresses and subnets in general, see
LAN Settings
on page
28
.
4.1.3
DNS and Domain Suffix
A domain is a location on a network, for instance
example.com
. On the Internet,
domain names are mapped to the IP addresses to which they should refer by the
Domain Name System. This allows you to enter “www.example.com” into your
browser and reach the correct place on the Internet even if the IP address of the
website’s server has changed.
Similarly, the CGN3 allows you to define a
Domain Suffix
to the LAN. When you
enter the domain suffix into your browser, you can reach the CGN3 no matter what IP
address it has on the LAN.
4.1.4
Debugging (Ping and Traceroute)
The CGN3 provides a couple of tools to allow you to perform network diagnostics on
the LAN:
Ping: this tool allows you to enter an IP address and see if a computer (or other
network device) responds with that address on the network. The name comes
from the pulse that submarine SONAR emits when scanning for underwater
objects, since the process is rather similar. You can use this tool to see if an IP
address is in use, or to discover if a device (whose IP address you know) is
working properly.
Traceroute: this tool allows you to see the route taken by data packets to get
from the CGN3 to the destination you specify. You can use this tool to solve
routing problems, or identify firewalls that may be blocking your access to a
computer or service.

4.1.5
Port Forwarding
Port forwarding allows a computer on your LAN to receive specific communications
from the WAN. Typically, this is used to allow certain applications (such as gaming)
through the firewall, for a specific computer on the LAN. Port forwarding is also
commonly used for running a public HTTP server from a private network.
You can set up a port forwarding rule for each application for which you want to open
ports in the firewall. When the CGN3 receives incoming traffic from the WAN with a
destination port that matches a port forwarding rule, it forwards the traffic to the LAN
IP address and port number specified in the port forwarding rule.
NOTE:
For information on the ports you need to open for a particular application,
consult that application’s documentation.
4.1.6
Port Triggering
Port triggering is a means of automating port forwarding. The CGN3 scans outgoing
traffic (from the LAN to the WAN) to see if any of the traffic’s destination ports match
those specified in the port triggering rules you configure. If any of the ports match, the
CGN3 automatically opens the incoming ports specified in the rule, in anticipation of
incoming traffic.
4.1.7
DMZ
In networking, the De-Militarized Zone (DMZ) is a part of your LAN that has been
isolated from the rest of the LAN, and opened up to the WAN. The term comes from
the military designation for a piece of territory, usually located between two opposing
forces, that is isolated from both and occupied by neither.
4.1.8
DNS
Domain Name Server (DNS) runs special-purpose networking software, features a
public IP address, and contains a database of network names and addresses for
other Internet hosts. DNS translates Internet domain and host names to IP
addresses. DNS automatically converts the names we type in the Web browser
address bar to the IP addresses of Web servers hosting those sites.
