Re: What is a good firewall tool?
Well i just resetup my firewall, actually still in the
process of adding things to it as time progresses.
First off, my opinion on GUI firewalls, youre adding
more processes to a firewall then what is needed. A
true firewall should have the least amt of processes
installed/running on it all the time.
What id suggest is make a really simple script like i
you first want to make your policy drop everything on
default, that will make it like its not online
iptables -P INPUT DROP
iptables -P FORWARD DROP
iptables -P OUTPUT DROP
then you want to enable special ports you want to
allow in ie
iptables -A INPUT -p tcp --dport 22 -j ACCEPT
that will allow ssh into it.
then you allow like ESTABLISHED,RELATED connections
etc, any other ports, you enable ip_forward if its a
gateway, and do the POSTROUTING cmd in many firewalls
its actually quite simple.

a very good program to port scan.
