Don't worry, thats not unusual ;-)

Be aware that is is most likely a very insecure setup. If you ultimately
trust your cutomers it's fine. But it's likely that you open up every
vserver and maybe even the host to everyone who can connect.
Your VNC implementation probably doesn't encrypt VNC traffic either, so
it's pretty easy to sniff passwords etc entered through VNC.
But that's getting a bit off topic for this list,
