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?
Maybe because using port numbers doesn't make sense for icmp packets, which is included in the rule when using -p all?
Looks like you have to specify two rules, one for tcp and one for udp.
