Help with open vpn routing

So after much hunting around the internet and reading, the only way this openvpn thing it going to work is with iptables and NAT packet translation. I’ve added a static route for my own vpn subnet back to mycloud vpn tunnel, but still no luck.

It just doesn’t look like the ipforwarding is working between the openvpn tun0 device and eth0 device on the mycloud device!

So, looked at ssh tunnelling, but that is only point to point … so not much good. 

Also looked at sshuttle; it looked interesting until I saw a youtube video and then it wasn’t.

So anyone installed the missing iptable kernel modules on mycloud at all?

Is it possible without it becoming a brick?
