I am looking into different firewall tools.
Well, I am looking to turn my Centos notebook into a NAT box, so that I 
can plug my corp notebook into its ethernet, and get access through my 
Centos notebook's wireless connection.  (yes the corp notebook has 
wireless, but they frown on us using it!)
I have started with Shorewall via webmin.  I suspect that since my main 
firewall is Astaro, I will figure out Shorewall.
But in an earlier post to this list, there was a reference to 
Firestarter (http://www.fs-security.com/).
Thing is there is no Redhat/Centos 5.0 rpm, only 4.x.
Anyone out there know if it will work?
