Hmmm -- it takes most people minutes.

No, they do not -- but you can disable the Mandrake iptables init script by:

	service iptables stop
	chkconfig --delete iptables

If you follow the instructions in the two-interface QuickStart Guide, then the 
*only* change you need to make to the Shorewall configuration (after 
overloading the initial /etc/shorewall files with those from the 
two-interface sample) is to add *two rules* for your caching nameserver:

ACCEPT	loc	fw	udp	53
ACCEPT	loc	fw	tcp	53


So if you are having problem, they likely aren't related to Shorewall.
