Hi @netblues, thanks for your response.
I agree it would be much easier if I connected to the VPS PFS from the VLANed VM. But the thing is I want to know how to make this using PFS. So let's start with some questions, as I might have gaps of knowledge:
Peer-to-Peer (Site-to-Site) OVPN connections: are they bidirectional? If I wanted to NAT Port Forward to this Interface which 'Redirect target IP' should I use?
thanks
