How to redirect all traffic from a ONLY Guest VLAN to a VPN

[DarkCorner]

Premise: I have never used a VPN to browse, not even from a PC or smartphone.
I have only used VPN to remotely access other devices on my network.

Now I would like to install a VPN so as to redirect all traffic from a Guest VLAN to this one, while LAN and DMZ traffic continues to pass over the WAN in the normal way.

I have read various documents and forum posts; I may have searched wrong, but it seems to me that all the suggestions are for directing all traffic to the VPN and not just to one VLAN.

Can you give me some suggestions or links to documentation?

There is currently no VPN server installed on my firewall (latest version).
I was also thinking of using ProtonVPN because it has a "Free" profile that I can use for testing.

I solved it myself by finding new documentation.
Thanks anyway.
