You could set up an SSH tunnel:
Google for it, there are a few links on this.
I've done it successfuly by setting up an ssh tunnel between
my linux box and my laptop, and the laptop and the db server
inside the firewall, IIRC. The laptop has the VPN access.
IAC, I was able to logon with sqlplus from my linux box, to
an internal database.
Pretty cool trick if you have a need for it.
