Turning off Ethernet firewall software<br />
Introduction<br />
If you are using an Ethernet network, read this topic to learn about the<br />
effect of firewalls and how to turn them off.<br />
To learn how this topic fits into the overall process of setting up an<br />
Ethernet network, see “Ethernet networking workflows” on page 39.<br />
Firewall defined<br />
A firewall is a security system that protects a computer on an Ethernet<br />
network against external threats.<br />
Types of firewall<br />
Hardware firewalls protect computers from threats outside the local<br />
network. Software firewalls prevent worms from propagating on the<br />
internal network.<br />
Sources of software<br />
firewall<br />
The computer controlling the VCode may have one or more software<br />
firewalls running on it. There are two software firewall sources to be<br />
concerned with:<br />
❑ Windows XP operating system has a built-in firewall that may be<br />
turned on by default or may have been turned on by someone in<br />
your organization.<br />
❑ Your computer may be running a separate firewall program that your<br />
organization has purchased and installed.<br />
Either of these types of firewall can prevent the devices on the network<br />
from showing up in the Discovered BioNet Devices dialog box.<br />
With dynamic<br />
IP addressing<br />
If your Ethernet network is using dynamic IP addressing, the firewall may<br />
block the request for an IP address from the VCode when it is turned on.<br />
With static<br />
IP addressing<br />
If your Ethernet network is using static IP addressing, the VCode<br />
software sends out a request for devices on the network to identify<br />
themselves, but the firewall may block the response.<br />
About turning off<br />
firewalls<br />
To turn off the firewall for your operating system, follow the directions in<br />
Windows Help and Support on your computer.<br />
To turn off a separate firewall program, follow the directions in the<br />
documentation that accompanies the program. You can either uninstall<br />
the program or stop it. If you choose to stop it, make sure that the<br />
program is not configured to start up again every time you restart the<br />
computer.
