I can not make "remote" debugging work over an openvpn connection (works on a "local" DB though)
In some previous versions (I think before 19.x) it was possible to create a reverse ssh tunnel "back" to the client
and use this with a fixed port. But that approach does not seem to work any more.
Sqldeveloper running on windows 10, firewall ports are not blocked so far i can tell (with firewall disabled makes not difference at least)
Any hints are welcome.
