So that setup effectively gives you an all-ports available connection (except 22) from your mobile device and anything that connects through it, like a laptop? The exit node would be the VPS.
Could I skip the home router and EoIP+VPN directly between mobile and VPS, for instance?
I am in a situation (restrictive firewall on ethernet/wifi, prefer personal mobile connection but it’s cgnat or something equally crap) this could be very useful for me.
