Every thought about trying 'Port Knocking'? Great Article on it,
http://www.linuxjournal.com/article/6811 If your decent with shell
scripting, you could write a script that checks your logs for attempts
on certain ports in a certain sequence, then opens up the port to the
ip address they came from. That should solve your problems with just
blatently opening the port and make it a little more secure.
