I thought it was better to REJECT all that you don't allow, on the
grounds that that's the expected behavior for an unbound port.

In other words, if I REJECT packets to, say, port 25, then to an
attacker running a scan it looks like I don't have a daemon listening on
port 25.  But if I DROP packets to port 25, then he knows I have some
kind of firewall in place, and might think I would make a more
interesting target.

Granted, if an attacker is specifically targeting my box, then it
doesn't really matter.  But if he's running a general scan over a bunch
of IPs, then the IPs that DROP packets will stand out, because the scan
will come to a screeching halt while waiting for the connection attempts
to timeout.
