    You need a vpn connection between the server and home to keep the client's IP.

    Do you need to tunnel protocols other than TCP? Because if not you can just use SSH Remote Port Forwarding.

    Anyhoo, this should be pretty straightforward considering you already have the VPN set up, take a look at this.

    Sorry I'm struggling to follow.... you have a vpn and a vps and then there is an ip address at your house (lan ip 192.x.x.x) port forwarding from your internal lan to the Internet is easy and you can change the external port so internal can be 7575 and external can be 8282

    Unless that's not what your trying to achieve

    on ubuntu box
    iptables -t nat -A PREROUTING -p tcp -m tcp -i ens33 --dport 7575 -j DNAT --to-destination 10.255.255.35:8282

    will packet oging to your home..

    uhm.. i don't know your home's vpn ip

    you don't need Masquerade line because it's source nat.
