I have a working connection to a vpn provider, i would however like to share those connections, with other machines on my sub-net, in particular devices that don't support openvpn, TVs for instance.
So my plan was to just set the machine that has the running VPN connection as the default gateway, for those systems that cannot do the VPN related things buy them selves.
I expect that i need to do some NATing, im sure its something simple

so what i have
Ubuntu client with TUN0, machine ipaddress 192.168.1.128, this is what i would like to route traffic through. Does this make sense?
