`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?
