Hi - simple question - is there a Firewall for Linux that will put my
ports into 'stealth mode'?

I'm basically looking for an equivalent to Windows' ZoneAlarm.

Sure, you've to DROP everything in your ports using iptables ;-)
If still using ipchains, you can DENY your ports.
Now you must look for a firewall builder if you're not going to write the
firewall scripts by hand, visit http://freshmeat.net

Simple, neat and effective. Just a shell script.

try <http://www.smoothwall.org/>. I bought an old P133 for 25,
installed smoothwall (took about 4mins!) and haven't touched it since
(and that was about a year ago!).

gives you a Web-based interface to dial-up, disconnect, see graphs of
I/O, etc. all machines behind it are protected as you require.

I'm not saying smoothwall is `best', but it's worked for me.

ipchains -I input -i <your interface> -p tcp --dport 0:1025 -j DENY
ipchains -I input -i <your interface> -p udp --dport 0:1025 -j DENY

where <your interface> is eth? ppp? or le?> replace the "?" with
the number of the actual card <usualy 0>
