There's very little support or documentation for any of us messing with External VPN's. I've been posting here looking for help for days now and rarely does anybody contributeOPNsense software is way overcomplicating things, as you've seen by simply trying to follow that selective routing guide, it should've been possible in less than half the steps. And once the guide is done and followed to the tee, they leave you completely dry with how to make use of it afterwards!

Is the tunnel up and can you ping the internal tunnel address at the other end from the firewall?Second NAT on the firewall won't be enough. Once the tunnel works you will need to NAT all oubound traffic to the public IP of the other end. And this must be done at the other end.
From where do you ping where? You need to open a shell on the firewall with SSH and ping the other side of the tunnel.
wgnetstat -rnplease.Also what does the WireGuard configuration on the VPS look like?
