On Firewalls
A firewall is a system that prevents unauthorized access to a local network from the outside.
When setting up the machine for a use over a network, disable the firewall of your security software
during the setup. Any firewall feature provided by security software may prevent proper setup or
communication over a network.
Note
z
If you disabled a firewall feature, disconnect your network from the Internet. You can do this by
configuring your access point or router not to connect to the Internet or WAN.

For information on the firewall feature of your security software, refer to its manual. In an office setup,
consult your network administrator.
