My "default" firealling method is to use a statefull firewall and
only allow responses to come back in.  Then as I need to depending on
the application I open up ports from the outside world.... that is
more secure than blocking this, blocking that, etc... as most people
need very little to come through (as a connection innitiator.. and
at least from a home user perspective).
