The following table describes the labels in this screen.

Gateway IP

This displays the IP address of the device to which the

CVE-30360 is connected over the

CATV

interface.

DHCP Lease Time

This displays the time that elapses before your device’s

IP address lease expires, and a new IP address is

assigned to it by the DHCP server.

System Time

This displays the current date and time.

TABLE 9:

The Cable > Password Screen

Enter Current Password

Enter the password with which you currently log into the

CVE-30360

This chapter describes the screens that display when you click

in the toolbar.

3.1

LAN OVERVIEW

This section describes some of the concepts related to the

LAN

screens.

3.1.1

LOCAL AREA NETWORKS

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 CVE-30360’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

28

).

The LAN is a separate network from the Wide Area Network (WAN). In the case of

the CVE-30360, the WAN refers to all computers and other devices available on the

cable (

CATV

) connection.

By default, computers on the WAN cannot identify individual computers on the LAN;

they can see only the CVE-30360. The CVE-30360 handles routing to and from

individual computers on the LAN.

3.1.2

LAN IP ADDRESSES AND SUBNETS

IP addresses on the LAN are controlled either by the CVE-30360’s built-in DHCP

server (see

DHCP

on page

27

), or by you (when you manually assign IP addresses

to your computers).

For more information about IP addresses and subnets in general, see

IP Addresses

and Subnets

on page

25

.

LAN

3.1.3

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 CVE-30360 allows you to define a

Domain Suffix

to the LAN. When

you enter the domain suffix into your browser, you can reach the CVE-30360 no

matter what IP address it has on the LAN.

3.1.4

DEBUGGING (PING AND TRACEROUTE)

The CVE-30360 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 CVE-30360 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.

3.2

THE LAN IP SCREEN

Use this screen to:



Configure the CVE-30360’s LAN IP address, subnet mask and domain suffix



Configure the CVE-30360’s internal DHCP server



See information about the network devices connected to the CVE-30360 on the

LAN.
