■ allows convenient connection to the computers that are to be
connected to the four LAN ports on the rear panel.
■ allows easy viewing of the front panel LED indicator lights,
and access to the rear panel connectors, if necessary.
Safety Information
WARNING: Please read the “Important Safety Information”
section before you start.
VORSICHT: Bitte lesen Sie den Abschnitt “Wichtige
Sicherheitsinformationen” sorgfältig durch, bevor Sie das Gerät
einschalten.
AVERTISSEMENT: Veuillez lire attentivement la section
“Consignes importantes de sécurité” avant de mettre en route.
When positioning your Router, ensure:
■ It is out of direct sunlight and away from sources of heat.
■ Cabling is away from power lines, fluorescent lighting fixtures,
and sources of electrical noise such as radios, transmitters and
broadband amplifiers.
■ Water or moisture cannot enter the case of the unit.
■ Air flow around the unit and through the vents in the side of
the case is not restricted. We recommend you provide a
minimum of 25mm (1in.) clearance.
Using the Rubber Feet
Use the four self-adhesive rubber feet to prevent your Router
from moving around on your desk or when stacking with flat top
OfficeConnect units. Only stick the feet to the marked areas at
each corner of the underside of your Routerl.
Using the Stacking Clip
The stacking clip allows you to stack your OfficeConnect units
together neatly and securely.
CAUTION: You can stack up to a maximum of four units. Smaller
units must be stacked above larger units.
To fit the clip:
1 Place your unit on a flat surface.
2 Fit the clip across the top of the unit, as shown in
Figure 5
(picture 1), ensuring that the longer sections of the
fastening pieces are pointing downwards.
3 Align the fastening pieces over the slots found on each side of
the unit.
15
4 Push the clip down gently to secure it, ensuring the fastening
pieces snap into the slots on the unit.
To fit another unit:
1 Rest the second unit on top of the clip and align it with the front
of the unit below.
2 Press down gently on the unit to secure it onto the clip, ensuring
the fastening pieces fit into the slots on the unit below, as

To remove the clip:
1 Remove the top unit together with the clip. If you hook a finger
around one of the the fastening pieces and then pull it gently
from out of the slot, the clip should come away with the upper
unit attached to it.
2 Push the clip in the center, so it bends towards the base of the
unit, and then separate once the clip is loose.
Before you Install your Router
Before you can configure the Router you need to know the IP
information allocation method used by your ISP. There are four
different ways that ISPs allocate IP information, as described
below:
Dynamic IP Address (DSL or Cable)
Dynamic IP addressing (or DHCP) automatically assigns the Router
IP information. This method is popular with Cable providers. This
method is also used if your modem has a built in DHCP server.
PPPoE (DSL only)
If the installation instructions that accompany your modem ask
you to install a PPPoE client on your PC then select this option.
Note that when you install the Router, you will not need to use
the PPPoE software on your PC. To configure the Router you will
need to know the following: Username, Password, and Service
Name (if required by your ISP).
Static IP Address (DSL or Cable)
The ISP provides the IP addressing information for you to enter
manually. To configure the Router you will need to know the
following: IP Address, Subnet Mask, ISP Gateway Address, and
DNS address(es).
PPTP (DSL or Cable)
PPTP is used by some providers, mostly in Europe. If the
installation instructions that accompany your modem ask you to
setup a dialup connection using a PPTP VPN tunnel then select
16
this option. Note that when you install the Router, you will not
need to use the dialup VPN on your PC anymore. To configure
the Router you will need to know the following: Username,
Password, and VPN Server address (usually your modem). You will
be asked for the IP Allocation Mode when you run the Setup
Wizard.

18
SETTING UP YOUR COMPUTERS
The OfficeConnect Secure Router has the ability to dynamically
allocate network addresses to the computers on your network,
using DHCP. However, your computers need to be configured
correctly for this to take place. To change the configuration of
your computers to allow this, follow the instructions in this
chapter.
If your computers are configured with static addresses (also
known as fixed addresses) and you do not wish to change this,
then you should use the Discovery program on the Router
CD-ROM to detect and configure your Router. Refer to “
Discovery” on page 79 for information on using the Discovery
program.

Choosing your LAN Settings
The LAN settings screen, shown in Figure 23 below, displays the
Router’s current IP address and subnet mask. If this is the first
time the Wizard has been run it will display the default address
and subnet mask.
Figure 23 LAN IP Address Screen
1 Enter your chosen IP address for the Router in the IP Address
field. This should be a private network so that it does not conflict
with IP addresses on the Internet. See “
page 83
.
Private IP Addresses” on
3Com recommends that you use the default IP address and
subnet mask unless you already have a network that uses
different values.
2 Enter your chosen subnet mask in the Subnet Mask field. This
should be large enough to contain all your computers and other
network devices. The default (255.255.255.0) allows for 254
devices including the Router.
3 If you are going to set up an IPSec VPN with another Router you
must set your subnet mask to 255.255.255.0. See “
Configuring
VPNs” on page 58.
Activating DHCP
The Router contains a Dynamic Host Configuration (DHCP) server
that can automatically configure the TCP/IP settings of every
computer on your network. The DHCP Server Setup screen is
shown below.
If you intend to use the Router to control the permissions of
individual machines on your network then you must use the
Router’s DHCP server to allocate addresses (or use static
addressing). If you use another DHCP server you may get
unexpected results. See “
PC Privileges” on page 50.
