using a tns connection over internet

I want to run certain apps from outside the local network, and i'm having some problems on how to go about it.

1. configuring a proxy.. on the client side i can only use the external ip of the proxy server. Then i have to open up a port. but how do i tell the proxy what machine to forward traffic to on a certain port?
2. is it safe? Is there any way for Oracle to tell which connection comes from the outside world? I don't wanna risk that someone can connect as a user with DBA-rights, for instance.

How do i handle this? Are there other considerations? perhaps other solutions?
