Lesson Summary
■ Windows Firewall is a software-based firewall built into Windows XP Professional.
Windows Firewall blocks all incoming network traffic except for solicited traffic
and excepted traffic.
■ You can enable or disable Windows Firewall globally for all network connections
on a computer, including LAN, dial-up, and wireless connections.
■ You can also enable or disable Windows Firewall selectively for each network
connection on a computer.
■ Windows Firewall allows you to configure a number of advanced options, including
the following:
❑ Enabling Windows Firewall logging to log network activity
❑ Creating an exception for a service or application to allow traffic through the
firewall
❑ Creating a custom service definition when a built-in exception does not suit
your needs
❑ Creating an ICMP exception so that the computer responds to traffic from certain
network utilities
■ Troubleshooting Windows Firewall typically involves enabling or disabling Windows
Firewall and creating exceptions so that specific network traffic is allowed
into the computer.
