I have at home my HomePc with OpenVpn-server installed. When I, with my laptop via 4g or wifi, connect via vpn I have access to my files on my HomePc and I'm able to browse the internet via the IP-address of my InternetProvider (185.2.2.2).
I have also a RaspBerry 3 with a VPNclient which is connected with NordVPN. I have installed squidproxy on this raspberry. When I browse on the internet with my HomePc I use the IP-address from NordVPN-server (65.4.4.4).
What I want is when I browse on the internet via my laptop (4G), connected via my vpnserver ( 10.4.0.3), using also the Ip-address from NordVPN-server (65.4.4.4) in stead of my Own internet Ip-address (185.2.2.2). (passthrough).
How to fix this?

Thanks
Bob
