Hello list,
I just started learning firewall setup with iptables
and found the following tutorial useful:

Hi,
Looks like a good idea.
What do you think about the ruleset proposed for a
typical web server firewall?
http://www.iptablesrocks.org/guide/ruleset.php
Ouch, that's pretty complicated (especially the stuff with TCP flags at
the beginning: iptables is a stateful firewall, the INVALID and
ESTABLISHED targets have been create to avoid such crap).
What do you think about the suggested Iptables Log
Analyzer: http://www.gege.org/iptables/
Not developed since 2002, works for linux 2.4 (no ipv6), uses text-based
logging ... I would say this is a pretty bad idea.
I'd suggest using ulogd [1] with a graphical interface, like NuLog [2].
Cheers,
Pierre
