Sure it is a pain but sometime you have to write everything from scratch. If you are setting up a cluster or complicated networking APF or other scripts are not useful.

And not to mention you can make some good money by providing customized solution
Yep monk you are right with every word thats why these days I am consintrating on iptables, but really its not easy.

by the way thanx for locating me to a job
