iptables / firewall

matto · 2008-12-07 14:36:51

Hi!
few week ago somebody tried to exploit my machine and i decided to use a firewall.
( http://bbs.archlinux.org/viewtopic.php?id=59550 )
Iptables syntax is quit hard (for me) so i used firewall builder to compile some rules.
I startet them , saved them with /etc/rc.d/iptables save and finally added iptables to my rc.conf.

iptables -L

tells me that they are active.
good work i thought , but how do i know if my rules work the way they should work?
Are there any tools to check that? nmap tells me that there are more open ports then there should be.
(but i think this is due to nmap ran via loopback on 127.0.0.1)
greeting matto

I get confused by iptables too. I just edit /etc/iptables/iptables.conf directly and run /etc/rc.d/iptables restart. Is there anything bad about that?

did u try configuring iptables with webmin? looks very clear and easy.

I recommend firewall builder. A gui to configure various firewalls, it outputs iptable-rules.
but i don´t think there´s something bad about configuring iptables by hand!

The arno-iptables-firewall in the AUR provides nice defaults and high configurability.
