I suppose it could be setup that way, but ours is not.

The only way to connect to a database from a local app
through the vpn ( for me anyway ) is to tunnel sqlnet
through ssh.

We could set it up to allow a certain range of ports
through, just as we do for other apps, but I don't
see any point in it, as I'm the only one that would
benefit from it.  :)
