You have a nerve [0/0]. Is pretty insecure. Guess would be easy to sniff the vnc
password and every guy with some ambitions will move the mouse only you
should move remotly.

Would suggest following simple way to make it more secure, also if you
have a static ip you can bind.

Find the position of the rules in /sbin/SuSEfirewall2 and modify this rules in order
to check the MAC-Adresse of your remote machine.

If you've further question how to, mail me.
