Help with OpenVPN tunnel without encryption

[VaCUm]

Hello! I have a OpenVPN tunnel that gives me 4 static IPs without blocked ports. I want to connect to the tunnel with PFsense and then use incoming NAT to my servers. I will then use outgoing NAT to forward outgoing trafic.

My operator gave me this
ifconfig X.X.X.16 255.255.255.192
port 6015
dev tap
comp-lzo
ping 15
verb 3
The other adresses ends with .81-83

Now to the problem The tunnel does not use encryption and i can therefore not connect to it.

Is it possible to add "No encryption" to the list?
