The following rule can't be applied iptables -A INPUT -p all --dport 80 -j DROP the above fails stating that --dport is not recognized. I'm trying to drop all traffic to port 80. If I provide a specific protocol it works. For example: iptables -A INPUT -p tcp --dport 80 -j DROP any ideas? -- Alan Angulo Systems Administrator Academic Computing East Stroudsburg University e-mail: alan@xxxxxxx Tel: (570) 422-3783
