Firewall Software

When you use the notebook for e-mail, network, or Internet
access, it is possible for unauthorized persons to obtain
information about you, your notebook, and your data. Firewalls
monitor all incoming and outgoing traffic on your computer by
including features such as logging and reporting, automatic
alarms, and user interfaces for configuring the firewall. To protect
your privacy, it is recommended that you use firewall software.
Your notebook comes with preinstalled firewall software. Refer to
the online Help in the firewall software application for additional
information.
Under some circumstances a firewall can block access to Internet
games, interfere with printer or file sharing on a network, or
block authorized e-mail attachments. To temporarily solve the
problem, disable the firewall, perform the task that is interfering
with the firewall, and then reenable the firewall. To permanently
resolve the problem, reconfigure the firewall.
