Sure, will update once i do it in my vbox. Actually i want to know whether is there any specific way to be followed, while writing iptables rules like,
1. Typing iptables straight from terminal and saving them
2. Or Adding rules in /etc/sysconfig/iptables file itself

Also, i would like to know which command should be used to save and restart iptables
iptables-save or /etc/init.d/iptables save or iptables-save > iptables // service iptables restart or /etc/init.d/iptables restart

Apart from that, can we edit firewall setting from gui also, while adding rules from terminal. Bcoz i found a strange issue, one of my colleague added an entry using gui firewall and all the settings in iptables got changed. Before doing that entry in GUI, the policy was set to DROP for input, but once after the firewall was edited using GUI, INPUT policy got set to ACCEPT.
