Linux Firewalls

["McKee, Charles" <charles.mckee () nmci-isf com>]

I have a quick question about an article I have just read in the latest
addition of Sys Admin. 
In the article it states that one can keep alive IPChains and Natd when
you do a shutdown -h on a Linux box, that is running Red hat 6.2. 
 
I was wondering will this work on for the latest versions of Linux and
what about the BSD family, Mandrake or even Solaris. 
 
Also if this is true, can your firewall be exploited or even the NatD
daemon. 
 
Has anyone ever actually tried this type of configurations and does it
work well.
 
Thanks
Chuck
