Can you use any other applications through the VPN tunnel, such as Remote Desktop to an MS Windows server or an ssh client to an ssh daemon on the remote network?

You want to first find out if this is a routing issue, or simply an Oracle-specific issue regarding NAT and redirection of dedicated server sessions.

There are docs in Metalink that cover this issue.

One method that I've used with success is to setup a dispatcher/shared_server on known, fixed ports such that no redirect occurs.

Another method has been to use port-forwarding in an ssh client (such as PuTTy).

This is likely a commonly encountered configuration issue that has well documented solutions.
