A more recent version of the same thing is at
http://iptables-tutorial.frozentux.net/chunkyhtml/c951.html
However neither version has been updated to include the new raw table,
which IIUC breaks that rule. Packets changed in the raw table do bypass
the filter table, and perhaps others as well. I'm not using raw yet,
thus am not sure of the details.
Joerg's response was accurate but might be said to suffer from TCP
tunnel vision: SYN is only used in TCP. Connection tracking supports
non-TCP protocols as well.
