Hi All, I am trying to present WUI for iptables with simple functionality such as add/delete rule. For adding rule, can i avoid adding the same rule again. Suppose, if the user tries to block ftp from outside. I will add iptable rule as below: iptables -A INPUT -p tcp --dport 21 -j DROP If the user tries to add the same rule again, can i somehow determine through iptables , if the rule is already added. Thanks and Regards, Pavan -- To unsubscribe from this list: send the line "unsubscribe netfilter" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
