Securing your network from Internet access

Check in the documentation of your wireless base station or router
whether it provides you with a built-in firewall and network address
translation (NAT), which provide security for an "always-on" broadband
Internet connection that is shared among the computers and devices on
your home network.
Computers on an Ad Hoc network may share an Internet connection that
is set up on one of the computers (ICS). However, a firewall is usually not
built-in and you should install one on the computer that is sharing the
Internet connection.
