Re: Firewalls?

Not entirely true - if you use one of the firewall distro's. You can have a firewall up in 4 mins, ok then 14. Look at e-smith, fli4l, smoothwall etc.

Linux
Assuming you want to put a machine between you and the net or move to the
OS, Linux offers a cheap (as in free) way to setup a firewall. It is the
most complex of solutions since a default linux install is not particularly
secure. Some knowledge of the OS and a lot of reading to work out what's
what is required to create a suitable firewall machine although newer
distributions have tried to create an easier interface to do this. Not
recommended unless you know the OS or have a patient friend to teach one or
a trustworthy one to go in and set up for you. You would also need to move
the DUN connection to Linux and install IP Masquearding and Port Forwarding
to perform an ICS type sharing of the connection. It is suitable as a
firewall for a network. Could be configured from the host PC or through a
suitably secured telnet SSH1/2 shell to the host from a client.


A hardware firewall is obviously the better bet in more secure environments,
but IME the NIS and previous AtGuard have been more thna enough for my
needs. Zone Alarm gets many recommendations but my personal experience leads
me to not concur with this recommendation. Out of those I have used and
tried, NIS is my winner. There were some others I tried briefly but they
either failed to install or had run time problems so I have ignored them
here.
