Most registered & legitimate services are below 1024...
actually, all inbound connections BELOW 1024. if you're connecting to an ftp (via port 21) the ftp data will not be transferred via 20/21 but via something above 1024.
so, with my current iptables-config, i will be able to connect to the ports 1-1024 but nobody else will be able to do this vice versa.
and of course all ports above 1024 (except some few) may be used for either inbound or outbound.
