Use the BIPAC-5100/5100W’s LAN IP address when configuring from the LAN.
10.1.3 System Timeout
There is a system timeout of five minutes (three hundred seconds) for either the console port
or telnet/web/FTP connections. Your BIPAC-5100/5100W automatically logs you out if you do
nothing in this timeout period, except when sys stdio has been changed on the command line.
10.2 Telnet
You can configure your BIPAC-5100/5100W for remote Telnet access as shown next.
10.3 FTP
You can upload and download BIPAC-5100/5100W firmware and configuration files using FTP.
To use this feature, your computer must have an FTP client.
10.4 Web
You can use the BIPAC-5100/5100W’s embedded web configurator for configuration and file
management. See the online help for details.
10.5 Configuring Remote Management
Click Remote Management to open the following screen.

DESCRIPTION
Server Type
Each of these labels denotes a service that you may use to remotely manage the
BIPAC-5100/5100W.

Port
This field shows the port number for the remote management service. You may
change the port number for a service in this field, but you must use the same port
umber to use that service for remote management.
Secured Client IP
The default 0.0.0.0 allows any client to use this service to remotely manage the
BIPAC-5100/5100W. Type an IP address to restrict access to a client with a
matching IP address.

Chapter 11
Universal Plug-and-Play (UPnP)
802.11b is only supported for the BIPAC-5100W
This chapter introduces the UPnP feature in the web configurator.
11.1 Universal Plug and Play Overview
Universal Plug and Play (UPnP) is a distributed, open networking standard that uses TCP/IP
for simple peer-to-peer network connectivity between devices. An UPnP device can
dynamically join a network, obtain an IP address, convey its capabilities and learn about other
devices on the network. In turn, a device can leave a network smoothly and automatically
when it is no longer in use.
11.1.1 How do I know if I'm using UPnP?
UPnP hardware is identified as an icon in the Network Connections folder (Windows XP). Each
UPnP compatible device installed on your network will appear as a separate icon. Selecting
the icon of a UPnP device will allow you to access the information and properties of that
device.
11.1.2 NAT Traversal
UPnP NAT traversal automates the process of allowing an application to operate through NAT.
UPnP network devices can automatically configure network addressing, announce their
presence in the network to other UPnP devices and enable exchange of simple product and
service descriptions. NAT traversal allows the following:
¾
Dynamic port mapping
¾
Learning public IP addresses
¾
Assigning lease times to mappings
Windows Messenger is an example of an application that supports NAT traversal and UPnP.
See the
Network Address Translation (NAT)
chapter for further information about NAT.
11.2 Cautions with UPnP
The automated nature of NAT traversal applications in establishing their own services may
Page 64 / 86
64
present network security issues. Network information and configuration may also be obtained
and modified by users in some network environments.
All UPnP-enabled devices may communicate freely with each other without additional
configuration. Disable UPnP if this is not your intention.
UPnP broadcasts are only allowed on the LAN.
See later sections for examples of installing UPnP in Windows XP and Windows Me as well as
an example of using UPnP in Windows.
11.2.1 Configuring UPnP
From the Site Map in the main menu, click UPnP under Advanced Setup to display the screen
shown next.
The following table describes the labels in this screen.
LABEL
DESCRIPTION
Enable the Universal
Plug and Play (UPnP)
Service
Select this checkbox to activate UPnP. Be aware that anyone could use a UPnP
application to open the web configurator's login screen without entering the
BIPAC-5100/5100W's IP address (although you must still enter the password to
access the web configurator).
Allow users to make
configuration changes
through UPnP
Select this check box to allow UPnP-enabled applications to automatically
configure the BIPAC-5100/5100W so that they can communicate through the
BIPAC-5100/5100W, for example by using NAT traversal, UPnP applications
automatically reserve a NAT forwarding port in order to communicate with another
UPnP enabled device; this eliminates the need to manually configure port
forwarding for the UPnP enabled application.
Apply
Click
Apply
to save your settings back to the BIPAC-5100/5100W.
Cancel
Click
Cancel
to return to the previously saved settings.
