It's just one of those "I don't like my users accessing things freely."  It's an
UNIX mentality that isn't shared by Novell nor Microsoft.

Well, if you have both Windows and UNIX clients, they you'll need to learn both.

That's because your life is most simple if you use the service the _client_
expects.  I.e. SMB for Windows, NFS for UNIX.

Oh, so you're not sharing the Internet connection on your network.  Good.

The best firewalls are the ones that don't do anything else.  I.e., don't use
software firewalls unless they are on a dedicated PC doing nothing else).

Most hardware firewalls (or software on a dedicated PC doing nothing else) are
configured via web browser.

See, that's the delima.  A "strong firewall" will prevent 90% of horrendous,
Internet-enabled Windows applications from working.  Most Windows application
developers don't know what they are doing, including Microsoft's own application
division, so they design these piss-poor protocols that hate firewalls.

The result is that they either don't work with firewalls, or firewalls must have
more "lienient" rules.

It's a Windows software firewall.  It's not nearly as good as dedicated hardware.

If you have an old 486 or Pentium with at least 8MB of RAM, check out IPCop:
   http://www.ipcop.org

The Linux kernel has a built-in firewall, at the network-level.  Nothing
available for Windows compares.  IPCop is based on Linux.  100% Web configured.
 Just grab the .iso CD image file, burn it with whatever burner software you
use, and boot it on the box.
