Joel;

[[If your network uses Internet Connection Sharing (ICS) to provide Internet
access to multiple computers, you should use ICF on the shared Internet
connection. However, ICS and ICF can be enabled separately. You should not
enable the firewall on any connection that does not directly connect to the
Internet. ICF is not needed if you already have a firewall or proxy server
on your network in your home or office.]]

[[If you are sharing an Internet connection, enable the firewall only on the
host computer that is connected to the Internet. The host computer appears
to the Internet as the only computer on the Internet, hiding the computers
in your home network.]]

[[If you have multiple network connections on any of your computers, you
should turn on Internet Connection Firewall for each connection. When you
turn on the firewall for each network connection, it can interfere with file
and print sharing and prevent your computer from finding other network
devices. To allow these types of uses, you can manually open network ports.
When network ports are left open, the protection provided by Internet
Connection Firewall for your computer is reduced.

Port is a networking term that identifies the point at which a type of
network traffic reaches your computer. The exact ports that you open depend
on the type of traffic you want to send and receive.]]
