What firewall daemon do you use? Shorewall, Bastille, etc.? What's the output of Code: iptables -L When the firewall is on?
hi falko hi falko, thanks for your reply. i really dont know about the firewall daemon I am using. But following is what I got from the command that you have asked me to type. Looking forward for your help.
