Fantastic, it is better than using 1000 words to describe it :)
However, there is some information lacking (see below)

What do the lines with the arrows and 1.0 mean?

1. Mention subnet mask for clarity.  From your numbering scheme, it
appears to be /16 but that is a guess
2. Mention clearly which node is the gateway to avoid ambiguity.
Again, from the diagram it seems to be 10.1.0.1.

VL does *not* figure out that you intend to do 'Nat on the 10.1.0.1 node.
And what attempts have you made to create it but fail?

You will have to script the firewall rules (iptables) and ensure that
they are inserted in the kernel at every boot e.g. in /etc/rc.local

There are several great sites that will help with creating the iptables rules.
Please search with key words "linux+iptables+nat"
