Firewall Protection
A firewall is a hardware device or software program that protects your network from unauthorized
access. It protects your system from hackers running programs, sending email, and gaining access
to your private information. The following types of firewalls protect your network and computers:
Broadband Router Firewall
 Windows Home Server Firewall
 Personal Firewall
 Firewall Ports
Broadband Router Firewall
The HP Data Vault 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 Data Vault—which keeps them from being seen outside the network.
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 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 protects the computer on which it is installed
from attacks from other computers within the network.
Firewall Ports
The following table lists the ports used by the server.
