Hello,

I am total beginner to Linux and I'm trying to learn iptables basics. I would like to learn how to close all ports but 80, 20, and that ports 22 and 10000 will be open only to my IP address.


OK,

here is what I got so far:

# Accept local (192.168.5.0/24) SSH traffic
$IPT -A INPUT -m state -p tcp --dport 22 ! --state INVALID -s 192.168.5.0/24 -j ACCEPT
$IPT -A OUTPUT -m state -p tcp --sport 22 --state ESTABLISHED,RELATED -d 192.168.5.0/24 -j ACCEPT


That will allow all 192.168.5.* addresses to access port 22. How Can I have only:

192.168.5.3
and
192.168.5.4

to access my 22 port. Tutorial I used is from:

Or maybe you should use GUI frontend called Firestarter which is very easy to manipulate. http://firestarter.sourceforge.net
