Too Long; Didn't Read
I have always been scared of IP tables. If you want to know the reason check out the <a href="http://ipset.netfilter.org/iptables.man.html" target="_blank">man page for the same.</a> Though I have heard from many people that IPtables are more robust and secure, I have never used them because it has always been daunting. I personally feel that if I am not comfortable with something like IPtables and still use it I might add more security holes while not leveraging the benefits it provides. So I have stuck to using ufw for now. It is for the same reason that I prerfer Ubuntu over other flavors. Familiarity breeds confidence and I know that I will make less blunders. Donot consider this as a promotion of Ubuntu over other more secure flavors, because it is not. It is just my personal preference.
