setting the Local UDP Port to 3842. If this still does not work, try Resetting Your USB
Server Hardware (as described later in this section). If you still cannot see your server,
proceed to the Troubleshooting:Network Issues sub section.

Troubleshooting:Network Issues
At this point, your Keyspan Server Utility software is communicating with a specific network.
Unfortunately, the network link between your computer and your USB Server is broken. The
following are suggestions on how to solve these network related issues.
Firewalls
A 'Firewall' is a piece of software or hardware that helps keep your network safe by preventing
hackers from getting inside your network and also by preventing you from sending private data to
outside networks (ie the Internet).
Firewalls are either hardware (a physical item on your network ie your DSL router) or software
(resides on your computer ie Windows XP's built-in firewall software). In most cases, these
firewalls are configured to only allow 'basic' internet traffic (web, email, ftp, etc.) to come in and out
of your network. Since the USB Server is a new product, these firewalls usually do not know
ABOUT KEYSPAN SERVER SOFTWARE network data and may prevent you from
communicating with your USB Server.
If you are using a firewall, configure the firewall software to allow UDP traffic on port 3842 as well
as allow TCP/IP traffic on port 3842. The USB Server uses both UDP and TCP/IP to
communicate. If you have configured your firewall to allow UDP and TCP on port 3842 and you:
• Cannot See Your Server: skip ahead to the Wireless LANs or Wired LANs sub section.
• Can See Your Server: Your firewall was preventing access to the Keyspan USB Server. If
you had to configure a software firewall on your computer, please note that you have allowed
only your computer to see your USB Server. If you configured a hardware firewall, test
other computers to make sure that they can the your USB Server.
Tech Note: We have included step-by-step instructions on how to configure the
software firewall that is built into Windows XP. You can find these instructions in the
Windows XP Firewall Configuration appendix in this manual.
Wireless LANs
If you have a wireless network, please make sure that your wireless base station has Ethernet
Bridging enabled. Ethernet bridging allow wireless computers to act as if they are directly
connected to a wired network. If this feature is not turned on, your wireless computers will not be
able to see that Keyspan USB Server where as your wired computers will have full access.
To test this, temporarily connect your wireless computer to your network via a wired connection (ie
