SUMMARY
When configuring a Windows 95 client to connect to an
ISDN Orbitor 500 using an ISDN Terminal Adapter, you should use
the Dial-Up Networking features of Windows 95. This article
describes the configuration required to enable an IP and an IPX data
connection between a Windows '95 client and an Orbitor 500.
If your configuration requires the use of only IP or
only IPX then simply ignore the non-applicable settings.
MORE INFORMATION
Dial-up Networking Basics
With this type of configuration the Windows 95 client will use
the Dial-Up Networking feature to establish a secure PPP connection to
the Orbitor. All of the networking information required is retrieved
from the Orbitor via the PPP negotiation process. The series of events
that normally takes place when a Windows 95 client calls the Orbitor are
listed below:
- The Windows 95 client will dial the Orbitor over ISDN using
the terminal adapter that is connected to the PC.
- The Orbitor will answer the call and ask the Windows 95
client to authenticate using PAP.
- The Windows 95 client will send the User Name
and Password as defined within the Dial-Up Networking entry.
- The Orbitor will use the User Name and Password to perform
PPP authentication and then cross reference the User
Name to a Remote Site Alias. The Remote Site will provide
the rest of the PPP configuration required to complete the
transaction.
- Using this method will allow many remote Windows 95 clients
to use the same Orbitor on a contention basis. The
Orbitor can accommodate 40 Remote Site Profiles, and
therefore can accommodate up to 40 remote Windows 95
clients serviced with a single Orbitor. When using
a single 64K ISDN B-channel per connection you may
have two simultaneous Windows 95 client sessions.
- The Orbitor will send the IP and/or IPX parameters from the
matching Remote Site Profile to the Windows 95 client.
- The Windows 95 client proceeds to log in to the rest of
the network or server.
ISDN Terminal Adapter (TA) Configuration
If your TA has the ability to define the protocols used on the
ISDN B-channels then you must set the operation to PPP. You should consult
the manual of the ISDN TA for further information.
Windows 95 Dial-Up Networking Configuration
The Dial-Up Networking entry must use the ISDN TA as the
modem, and therefore you must specify the appropriate COM port related
to the TA.
To create a new Dial-up Networking (DUN) entry, double-click the "My Computer"
icon that is located on your Window's desktop. Once opened, double-click
on the Dial-up Networking icon. You may then select the "Make New Connection"
icon. Follow the instructions accordingly.
Within the properties of the DUN entry there is a "Server Types" tab
that should have the following settings:
- Type of Dial-Up Server - PPP
- Advanced Options
- Log on to Network - this will depend upon your
specific application. If the client is to be
logging in to a server then this should be
checked.
- Enable Software Compression - unchecked
- Require Encrypted Password - unchecked
- Allowed Network Protocols
- NetBEUI - unchecked
- IPX/SPX Compatible - checked if corporate network
is using IPX
- TCP/IP - checked if corporate network is using
IP
- TCP/IP Settings
- Server Assigned IP Address -
selected
- Specify Name Server Addresses -
selected
- Primary DNS - IP address
of the primary domain
name server on the
corporate network
- Secondary DNS - IP
address of the secondary
domain name server on the
corporate network
- Primary WINS - IP address
of the primary WINS on
the corporate network
- Secondary WINS - IP
address of the secondary
WINS on the corporate
network
- Use IP Header Compression -
unchecked
- Use Default Gateway on Remote
Network - checked
Once you have entered the proper parameters into the DUN entry, make
sure you save it properly, giving it a name that is appropriate for the
application.
Common Orbitor Configuration
The Orbitor has been designed to be as simple to configure
as possible. The following displays the configuration entries
required beyond the default parameters.
- Configuration -> Internet Set-up Menu
- IP Address & Mask - a valid IP address on the
corporate network as well as the valid address
mask
- Default Gateway - the IP address of the default
gateway of the corporate network.
- Configuration -> IP Routing Set-up Menu
- ARP Proxy - enabled. This allows the Orbitor to
respond on behalf of the remote Windows 95 client
and pass the IP traffic through.
- Configuration -> WAN Set-up -> Security Set-up Menu
Remote Site Profile Orbitor Configuration
This is the configuration required for a Remote Site Profile
which will be used when the Windows 95 client dials in and is
authenticated. If more than one Windows 95 client will be dialing
in to the Orbitor then a Remote Site Profile must be created for
each client.
The Remote Site Profiles are created and edited within the
Configuration -> WAN Set-up -> Remote Site Set-up Menu. The
following commands are referenced from the Edit Remote Site menu
level.
- Remote Site Alias - this MUST be set to the same as the User
Name used in the Dial-Up Networking on the client Windows
95 machine.
- Security Parameters
- Incoming PAP Password - this MUST be set the same
as the Password used in the Dial-Up Networking on
the client Windows 95 machine.
- Protocol Set-up
- IP Parameters
- Link IP Type - unnumbered
- Peer IP Address - this must be defined as
a valid IP address on the corporate
network and have a (32) mask.
- IPX Parameters
- Link IPX Type - numbered
- IPX Net - this must be set to a unique
IPX network number.
- Bridge Parameters
- Bridge Enabled - disabled
- CCP Parameters
- Compression - disabled
Newer versions of Windows '95 networking support
the use of LZS compression. As such this parameter
may be enabled.
- BACP Set-up
Repeat the above steps for each remote PC to connect to the Orbitor.
