In this howto, I will set up a VPN between a vyos gateway and an openvpn server hosted by a scaleway openvpn instance. The purpose of this is to hide my entire network behind a scaleway ip address.
Launch an openvpn on a C1 instance with a public ip address.
Openvpn server certificates will take some time to be fully generated. We can check that with scw-ovpn status:
# scw-ovpn status
