Comment on How can I set up a VPN that will use the client IP address for the connection?

I think that it’s similar to the “Normal VPN without NAT”, but I want it to preserve the client IP all the way through to the server that the client wants to connect to (in other words, the website that the client wants to access will receive the IP of the client, not the VPN server).

So there's three problems you are very likely to encounter.

Most providers now almost certainly filter their egress for netblocks under their control to prevent ip spoofing. So it's likely the packets would never make it out at all.

2: if it does work the return path would be over the normal Internet route and not via the vpn. Only the sent packets would go via the vpn host.

3: if the client is behind nat the router will not recognise the response packets as belonging to an open connection and will drop them.

I'm really not sure what your intention is.

Where is the server located? Are you looking at an intranet location or internet?

Is the client connected to the VPN concentrator via IPv4 or IPv6?

Is the VPN concentrator connected to the server via IPv4 or IPv6?

What you ask may be possible depending on those answers.
