Using the Server 6-23
information. The following types of firewalls protect your network and
computers:
•
Broadband router firewall
•
Windows Home Server firewall
•
Personal firewall
Broadband router firewall
The HP MediaSmart Server requires a broadband router. Broadband routers
allow multiple computers and devices to share an internet connection using
NAT (Network Address Translation) technology. NAT allows all the computers
and devices on your network to use a single internet connection ( IP address ).
NAT acts as a firewall by masking the real IP addresses of your network
components—including the HP MediaSmart Server—which keeps them from
being seen outside the home.
Some broadband routers implement Stateful Packet Inspection (SPI), which
adds enhanced security by examining each packet of information before
allowing it into the network. SPI can prevent advanced forms of incursions like
Denial of Service attacks.
Windows Home Server firewall
Windows Home Server includes Windows Firewall, which protects
communications between the server and the computers on your home
network. This firewall is configured to allow remote access. It is not
configurable by the user.
Personal firewall
A personal firewall is a software application that protects an individual
computer. Because a personal firewall is behind the broadband firewall, it
will protect the computer on which it is installed from attacks from other
computers within the network.
