Well I did a practical test ....... I installed Tiny Personal Firewall on my
girlfriends win2k machine, explained what the options meant and why you
should use em. Now she aint dumb, but after a couple of days of listening to
occasionally outraged howls I checked the configuration..... essentially it
was "allow all from any to any". When I asked her why, she said "it was just
too annoying having to decide from which machine to which and sometimes you
had to allow any and sometimes not so it was just easier......."
Until the default installs and actual practices of these products get smarter
they will remain at best, of limited use.
p.s this aint a windows issue..... I have seen the same phenomena on unix
based firewalls as well.
