Questions to Migrate OpenVPN Servers legacy to Instances New

[beneix]

I recently migrated from the "legacy" OpenVPN client configuration to the "instance" one.

I have an existing, working client setup under legacy that it would be nice to be able to migrate, but since the old one was set up with the help of the wizard and includes both the VPN setup, firewall rules and a dedicated interface, I am a bit daunted how to replicate the legacy client in the new Instances setup, without the wizard to guide me.

The documentation I found mentions two examples (site-to-site tunnel and road warrior) but neither fits my scenario. I just need to route traffic from a specific client on my LAN to a tunnel to my VPN provider.

Has anyone found improved documentation to guide them?
