I think the technical reason it gave the "option unknown" response is because 
those options (--dport, --sport) only become available to iptables when the 
specific protocol module (tcp, udp) gets loaded.  If you don't specify the 
protocol, the protocol module doesn't get loaded, and iptables doesn't even 
know the --dport option exists, thus the error.
