OpenVPN via stunnel: disable redundant encryption in openvpn?

Question

openvpn

Allowed OpenVPN traffic through the stunnel SSL tunnel . So it is necessary.
Everything is done right in stunnel : signed certificates, encryption, compression.
OpenVPN is used here in fact as a solution for connecting local subnets.
The question gnaws - we have a rather large overhead, because in OpenVPN, as in stunnel, both encryption, authentication and compression are included. It turns out double encryption and so on.
Question:
Should I disable encryption, compression, etc.? at the OpenVPN level as redundant? Is the stunnel level sufficient ?

Answer 1

You checkers or go? Encryption is never enough for the paranoid.
But the developers of OpenVPN took care of:

cipher none
auth none

But I would throw out stunnel.
