Rather than configuring your Nautica router to connect into an
ISP (Single Host Addressing) or as a Cul-de-sac router, it is
possible to configure the unit to act as a standard router.

As a standard router, the Nautica unit you have purchased sends
and receives information from the network and then passes this
information either to another router, or to a relevan t host address.

Basic Procedures

Nautica Wizard allows you to configure your Nautica units
simply and efficiently. More advanced router users may prefer to
configure their units using Nautica Router Software Release 4
(BCC).

If you would like to use the Release 4 software, refer to the
Nautica Router Software Release 4 documentation on the CD that
comes with your Nautica product.

This chapter contains the following sections:

The Nautica Wizard Window page 6-6
Basic Nautica Wizard Operations page 6-11

page 6-2

118814-A Rev. A 6-1

Issue 1
Nautica Configuration Wizard Reference Guide

Important - Please Read

Use of an ISDN router over a public ISDN network are usually on
a pay-as-you-go basis. You pay for the time that your ISDN link
is connected, although some suppliers also charge for every call
attempt.

Your ISDN router makes calls when there is one or more packets
to send to a remote network. In order to reduce the amount of
ISDN calls this can generate, it is important that you read the rest
of this section. The options outlined here can dramatically reduce
the amount of automatic ISDN calls made by your router.

Your Nautica router comes with a software package called
Nautica Watch (Chapter 15). Nautica Watch allows you to
monitor the activity on your router. The LED on the front of the
router also shows when the router is in use. The green LED will
flash continuously when the router is in use. If this happens when
you are not actively using your PC, then the PC or an application
on the PC is connecting to a remote network resour ce.

If you are in any doubt at all about any of the following points, or
the operation of your router, contact your local ISDN supplier for
advice.

E-mail Clients

Most TCP/IP based e-mail clients can be configured to check the
mail server for new mail at set intervals. This is known as polling.

If you are locally attached to a mail server, it may be appropriate
to poll for e-mail every fi ve minutes or less. These rules change if
you are remotely connected to a mail server via an ISDN router. It
is not appropriate, for example, to have the router calling the
remote mail server every five minutes to check for new mail.

6-2 118814-A Rev. A

To this end, it is recommend e d that you configure your e-mail
client for manual polling (where you press a button to check for
e-mail), or for a longer polling interval, such as once every hour.
Be aware though, that even with an hourly polling setting, the
router will make one call every hour. If you leave your PC and
router running overnight, this wo uld mean 24 calls every day,
even if you have no new e-mail.

Remotely Mapped Drives

In most popular PC operating systems, it is possible to map
virtual drives (such as J:) to file servers on the network. If you
map network drives over a remote ISDN connection, problems
can occur.

Issue 1

Basic Procedures

Every time you open a file, or move into a new folder, it is like ly
that the PC may request the current status of all drives and bring
up an ISDN call to achieve this.

For this reason, it is recommended that you do not permanently
map network drives over a remote ISDN connection.

Similarly, if you browse the Network Neighborhood over a
remote ISDN connection you will incur ISDN call charges.

File and Print Sharing

Many workgroup functions, designed to allow resource sharing
on a local network, use a periodic announcement/update
mechanism which causes frequent ISDN calls if used over a
remote ISDN connection. In order to avoid this, it is
recommended that you turn off file and print sharing on your PC.

To achieve this, do the following:

1. Click on the Start Button.

2. Choose Settings > Control Panel.

3. Double click on the Networks icon.

4. Click on the File and Print Sharing button.

118814-A Rev. A 6-3

Issue 1
Nautica Configuration Wizard Reference Guide

5. Deselect both options in the File and Print Sharing
window:

Figure 6-1. File and Print Sharing Window

6. Click on the OK button in the File and Print Sharing
window.

7. Click on OK in the Networks window.

8. Close down the Control Panel.

9. It may be necessary to reboot your PC at this time.

Graphical FTP Using “Keep Alive”

Traditionally FTP servers time out (or end) an FTP session if
there is no activity after a few minutes. Most command line FTP
clients take no steps to avoid this timeout. Some of the new
graphical FTP clients, howe v er , mak e frequent read (or k eepaliv e)
requests to keep the FTP sessions alive.

This option is fine for local network access and leased line
Internet browsing, but it can cause your remote ISDN connection
to stay up permanently.

If you use such FTP clients, be aware of this problem and close
down remote FTP connections once you have finished
transferring files.

6-4 118814-A Rev. A

Web Browsers

When you are browsing the web, many sites use “push”
technology. This feature opens a permanent channel between the
web site and your PC in order to update sound and graphic files
continuously. Using a remote router, such sites will keep your
ISDN connection open.

Other web sites cause your browser to refresh the screen at
regular intervals, for example, every 30 seconds. Again, this can
cause a link to stay open.

In order to minimize the ef f ect of these data streams, do no t leave
your PC unattended when it is in a web site and close down all
Internet connections when you have finished with them. When
browsing the web, be aware that ISDN calls are being made.

Configuring Paths

Paths are important in a Nautica router. They tell the unit
information about how to reach a specific destination. When a
unit is configured, there are two paths shown automatically; the
LAN01 path and a path called RemotePPP.

LAN01 is the path to the local network and is learned by the unit
automatically. RemotePPP is the path to the ISDN number setu p
when using the Installation Ass istant (Chapters 1 to 4).

This chapter includes the following sections:

The Path Table

As the unit makes and receive s calls it will learn new paths, and
these will be displayed in the Paths table as shown in Figure 8-1
The paths learned by the Nautica router will be deleted by the unit
automatically when they become blacklisted and unused (page

7-7).

To view the Paths table, do the following:

1. Select the unit that contains the paths yo u want to view in
the Nautica Wizard window (page 6-6

.

).

2. Click on

Advanced > Paths

3. The Paths table (Figure 8-1

RIP Parameters

Routing Information Protocol (RIP) specifies how information is
to be routed across your Nautica unit. Specify here the type of
RIP support you require and the direction in which that support
will operate.

118814-A Rev. A 8-5

Issue 1
Nautica Configuration Wizard Reference Guide

Parameter: Support

Default: Rip1 Compat (Single Host addressing and Standard

Routing), None (Cul-d e-sac Routing)

Options: Rip1 Compat, Rip1, Rip2, Rip1 Subnet, None

Function: This is the type of IP support used on this path

Instructions: The optio ns for this parameter are as follows:

• Rip1 Compat: RIP2 packets are broadcast. This

option is the RIP1 Compatibility option as specified
in RFC 1723 and is most likely to work with older
RIP1 implementations where the new RIP2 features,
like subnet masking, may be useful.

• Rip1: RIP Version 1 packets are broadcast as per

RFC 1508.

• Rip2: RIP Version 2 packets are multicast to

224.0.0.9 as per RFC 1723.

• Rip1 Subnet: This is a modified version of RIP1

mode which allows Nautica routers to work in
networks where RIP1 must be used due to an
installed base of older routers. RIP1 packets are
broadcast, but when network routes are learnt via
RIP, the Nautica router applies a subnet mask as
follows:

If the route is within the same “natural” network as
the current router, the subnet mask of the LAN01
interface is used; otherwise the “natural” subnet
mask is applied to the route. This allows correct
operation of a router in a subnetted environment
where RIP1 is used.

• None: Selecting this value will turn RIP support off.

The unit will not send or receive RIP.
