Introduction

The BayStack Instant Internet unit is a network gateway system that enables you
to access the Internet safely and efficiently, providing management tools that
allow you to track and block u ser ac tivi ties. The Inst an t Int ernet unit c onnect s any
type of LAN to the Internet using only a single IP address, thereby saving you
time and money.

This chapter provides information about the types of network environments in
which Instant Internet works as w ell as the services that Instant In ternet provides
for your network.

Instant Internet is an adaptive solution

Instant Internet is an adaptive network solution because it functions regardless of
whether you are operating in an IP or IPX environment. For example, if you plug
a unit into an IP net work, th at unit isolates t he IP networ k from the I nterne t. If you
plug that same unit into an IPX network, the unit acts as a gateway to the Internet.
This means that yo u do not have to inst al l TCP/I P on your workstati ons . Agai n, if
you plug that same unit into a network mixed with IP and IPX workstations, the
unit both isolates the IP workstations from the Internet and acts as a gateway to
the Internet for the IPX workstations.

Another way in which Instant Internet adapts to your network is by adopting the
users and groups already set up on your network. This makes administering
Instant Internet easy.

20 Chapter 1 Introduction

How Instant Internet can function in your network

Before you install the Instant Internet unit, you should understand your network
environment and how the unit functions in the network.

Instant Internet can function in your network in three ways. It can:

• Provide security – You can isolate your network from the Internet to help
ensure network security. You do this for three reasons:

— To prevent Internet users from outside your organization from seeing

internal IP addresses.

— To protect your network from being accessed by intruders or hackers.
— To permit remote LANs to communicate with your LAN over a virtual

private network (VPN) using IP security (IPsec).

• Control Internet access – You can restrict your users’ access by date and
time, and you can restrict access to certain sites or news groups.

• Ease admi nistration – Instant Internet allows you to adopt the users and
groups you are already using from your directory services.

IP networks

For security purposes, on an IP network, you may want to isolate your network
from the Internet. You can isolate your network from the Internet by configuring
the network workstations to go through a router before accessing the Internet.
However, using a router to isolate the LAN can be very time-consuming to set up
and maintain because each LAN user must have a “legal” IP address and be
protected from hackers. Instant Intern et, on the ot her hand, makes it easy t o iso late
your IP network from the Internet by using address translation to translate illegal
(reserved private) LAN workstation IP addresses into legal IP addresses.

You can also use IP security (IPsec) to create a virtual private network (VPN).
A VPN is a special type of connection that permits remote users or L ANs to
communicate with another LAN over a public network, such as the Internet.
When you set up a VPN, you are essentially using a public network as your own
private, secure network.

On IP networks with IP workstations, there is virtually no limit to the number of
application sessions (instances) that can access the Instant Internet unit.

209226-B

IPX networks

An IPX network is automatically secure bec ause there is no IP traffic o n the
network. In this type of network, Instant Internet provides quick and easy access
to the Internet. On IPX networ ks with IPX workstations, Ins ta nt In ternet supports
up to 250 application sessions.This means that IPX workstations can access the
Instant Internet unit using up to 250 application instances.

Chapter 2
Understanding the installation environment

When the Instant Internet management software is installed, it samples the tra ffi c
on your network to determine how to configure itself. However, the installation
process also requires some manual configuration when you use IP. Before you
begin the installation process, there are some concepts and information to
understand and some decisions to make if you are using IP. If you are using the
IPX network protocol, yo u do not need to per form any manual configu ration, refer
to “IPX workstations” on page 28.

The information in this chapter and the installation flowchart in Figure 1 on

page 31 will help you understand where to begin.

Understanding your local network environment

In order to use all or some of the options available with Instant Internet you must
understand how to set up your local network environment. Use the following
guidelines to determine which installation procedures to follow.

Understanding IP addressing

An IP (Internet Protocol) address is a numeric identifier for a computer or device
on a TCP/IP (Transmission Control Protocol/Internet Protocol) network. IP
addresses enable computers to talk to each other. IP addresses follow the format
nnn.nnn.nnn.nnn where nnn is a number between 0 and 255, for example,

134.177.3.28 or 10.1.1.1. Both servers and workstations on a network must have
IP addresses.

Installing the BayStack Instant Internet Management Software Version 7.11

24 Chapter 2 Understanding the installation environment

There are two types of IP addresses:

• Dynamic – A dynamic IP address changes. Dynamic IP addresses are

randomly assigned to computers by an IP address server as the computer
needs it. Usually there is a particular range (or scope) of IP addresses that
your network uses. With dynamic IP addressing, a computer can have a
different IP address each time it connects to the network. Other devices need
to know the computer’s IP address so that they can communicate with it. The
IP address server manag es the ass ignment of IP ad dresses t o the workstat ions.

• Static – A static (or fixed) IP address does not change. It is assigned to a

computer permanently. The computer has the same IP address every time it
connects to the network and is known to ot her devices on the network by that
IP address. Because the Instant Internet unit on your network is also the
gateway to the Internet, it must have a LAN-side static IP address.

Understanding DHCP servers

The IP address server that manages the dynamic IP addresses is called a DHCP
(Dynamic Host Configuration Protocol) server. You can set up Instant Internet to
be your network’s DHCP server and let it do the work of assig ning IP addres ses to
the workstations on your network as needed. This is the recommended
configuration.

When you set up the Instant Internet unit as a DHCP server, configure each of
your workstations t o get th eir new IP add resses ass igned by Instant I nternet . Refer
to “Preparing a network with no TCP/IP and no BootP or DHCP server” on

page 81.

If you already have a DHCP server, you must configure the DHCP server to use
the Instant Internet unit as the gateway and DNS proxy for the workstations. Refer
to “Preparing a TCP/IP network with an existing BootP or DHCP server” on

page 76.

209226-B

Chapter 2 Understanding the installation environment 25

Understanding gateways and DNS proxies

When you access Internet Web sites through the Instant Internet unit, the unit
functions as both a gateway to the Internet and a DNS proxy:

• Gateway – A gateway is a system that links different networks and enables

them to communicate with each other. Instant Internet is the gateway that
links your company’s network to the Internet. Depending on your
configuration, you may need to confi gure yo ur workst atio ns to use the Ins tant
Internet unit as their gateway to the Internet.

• DNS Proxy – A DNS (Domain Name Service) proxy translates

human-readable domain names into computer-readable IP addresses. For
example, the domain na me www.nortelnetworks.com for the Nortel Net works
Web site might translate to the IP a ddr ess 134.177.3.28. After Inst ant In ternet
translates a domain name into an IP address, the workstations on your
network can communicate with the Web site associated with that IP address.
Depending on your configuration, you may need to configure each of your
workstations to use Instant Internet as their DNS proxy.

Understanding static IP addresses

If you are already using static IP addresses for your network workstations, you
have two options. You can:

• Change from static IP addresses to dynamic IP addresses by setting up the
Instant Internet uni t as a DHCP se rver. This is the recommended
configuration. If you do this, you must configure each of your workstations
to allow the Instant Internet unit to assign their IP addresses.

• Continue to use static IP addresses. If you do this, you must also assign a
static IP address to the Instant Internet unit and configure each of your
workstations to use the Instant I nternet unit as th e gateway to the Internet and
as the Internet DNS proxy. Refer to “Preparing a TCP/IP network with static

IP addresses (no BootP or DHCP server)” on page 82.

Installing the BayStack Instant Internet Management Software Version 7.11

26 Chapter 2 Understanding the installation environment

Understanding how Instant Internet works with an existing
IP address server

Only one IP address server is allowed on a network—either your existing BootP
or DHCP server or the Inst ant I nterne t unit . If you a lready have a Boot P or DHCP
server or do not want to use Instant Internet as a DHCP server, you must assign a
static IP address to th e Instant Internet unit and then be sure the DHCP option for
obtaining an IP address is automatically enabled for your workstation. See

“Setting a workstation to get its IP address from Instant Internet or your existing
DHCP server” on page 87. You have two options when assigning a static IP

address to Instant Internet. You can:

• Use the Instant Internet unit’s MAC address to reserve a static IP address for
Instant Internet before you begin the installation. For more information, see

“Assigning a static IP address to Instant Internet using a BootP or DHCP
server” on page 77.

• Allow your existing DHCP server to assign a dynamic IP address to the
Instant Internet unit during the installation and then turn that dynamic IP
address into a static IP address.

Either method accomplishes the same task of assigning a static IP address to
Instant Internet.

After you assign a static IP address to the Instant Internet unit, you must do two
things on your DHCP server:

1 Exclude that s tati c IP addres s fro m the ra nge (or sc ope) of IP add resse s on the

DHCP server.

2 Configure your DHCP server to use Instant Internet as the gateway and DNS

proxy. Your DHCP server then points the workstations to use Instant Internet
as their gateway and DNS proxy, see “Configuring your DHCP server to use

Instant Internet as th e gateway and DNS pro xy” on page 78.

For details on setting up your network to use a DHCP server other than Instant
Internet, refer to “Preparing a TCP/IP network with an existing BootP or DHCP

server” on page 76.

• If you are using stati c IP addr es ses and do not want to use the Instant Inte rnet
unit as a DHCP serve r, you must configure the worksta ti ons t o us e t he Instant
Internet unit as their gateway and DNS proxy (see “Configu ring a wor kstatio n

to use Instant Intern et as the gateway and DNS proxy” on page 89).

• If you are using the Instant Internet unit as a DHCP server (page 87), you
might need to forc e t he wo rkstations to accept the new network c onfi gur at io n
information that the DHCP server provides (see “Setting a workstation to get

new information from the Instant Internet unit or your existing DHCP server”
on page 88). This is the recommended configuration.

• If your network is configured for pr int er and file sharing o nly and if you have
not set up any type of networking scheme, you must configure the
workstations to obtain an IP ad dress from the Instant Internet unit. Using a
DHCP server is normally the default setting for the Windows 95,
Windows 98, and Windows 2000 operating systems.

• If you are using an existing DHCP server, you must configure the
workstations to accept the new network configuration information that the
DHCP server provides (page 87).

You can prepare the workstations before you begin configuring the Instant
Internet unit or you can prepare them at the same time that you install the
workstation software. For details on preparing the workstatio ns, refer to

“Preparing a workstation with TCP/IP” on page 83.

IPX workstations

If you run the Instant Int ernet soft ware instal lation wit h no command line opti ons,
Instant Internet automatically installs the software for an IPX network under
either of the following conditions:

• The IPX version of the Instant Internet workstation software has previously
been installed.

• TCP/IP is not installed.

If TCP/IP is installed and the IPX version of the Instant Internet workstation
software has not previously been installed, the Instant Internet management
software installation program installs the software for a TCP/IP network.

Note: If Instant Inte rnet detect s both TCP/IP and IPX o n the workst ation,
you are given an opportunity to choose which installation to perform on
the workstation. You can force the type of installation by selecting
