    `man iptables`:

    icmp
          This extension is loaded if `--protocol icmp' is
          specified. It provides the following option:
                                                                                    
           --icmp-type [!] typename
                  This allows specification of the ICMP type, which
                  can be a numeric ICMP type, or one of the ICMP type
                  names shown by the command
                   iptables -p icmp -h

    iptables -A INPUT -p icmp --icmp-type echo-reply -j DROP
    iptables -A INPUT -p icmp --icmp-type destination-unreachable -j DROP

    gibi mi?
