The Matrix setup program offers to open these ports for
you in the Windows Firewall. It does not do this for other
firewall products.
Network traffic over these ports can also be blocked by
what is called a proxy server. Whether or not a network
has a proxy server that stops traffic on these ports, port
8080 in particular, is a question for the facility IT person-
nel.
The ports listed above are the defaults. If they are
changed for any reason, corresponding changes must
be made in the firewall settings to allow traffic over the
new port numbers. Changing the port numbers may be
necessary if, for example, another application is already
using these port numbers. Graco strongly recommends
that IT personnel familiar with the network are involved
with this configuration change.
Windows XP Security
The following security-related configuration settings are
not required but are recommended for all Matrix PCs:
1. Be sure a user name and password are required to
access the operating system.
2. Ensure the password-protected screensaver is
enabled and set to automatically activate after 15-30
minutes of system inactivity.
3. Change user passwords on a regular basis and
choose passwords that are difficult to guess.
4. Use anti-virus software to protect against viruses.
Some anti-virus programs are bundled with other
security software, including other security tools such
as pop-up blockers and firewalls. Take note of the
recommendations in the sections titled Special
Considerations for Pop-up Blockers on page 4
and Special Considerations for Firewalls on page
6.
5. Be sure the system is kept up to date with Microsoft
XP updates and service packs.
6. Use a firewall. As mentioned in the section titled
Special Considerations for Firewalls, take care to
allow for continued operation of Matrix by not block-
ing the network ports Matrix needs to use.
