I'm rather rusty on the details of this, but isn't the correct way to
handle this to have <server> publish an ARP route indicating that it
provides routing to (the IP space containing) <ADSL client>?

Any mere proxy or VPN hosted at <server> will allow <ADSL client> to
transparently establish connections, but won't allow <full internet>
to reach the IP address of <ADSL client> (nor anything else in
<Limited internet>).  Maybe that's not needed here.
