tinc is fully capable of traversing NATs automatically and transparently;
it implements techniques such as UDP hole punching that are specifically
designed to do just that.

The only requirement is that you have *some* nodes on your graph that are
not subject to NATs. In your case that would be your linux boxes. If you
add your laptop and Windows machine to that graph by establishing tinc
connections between them and their respective linux boxes, these new nodes
that are behind NATs will automatically leverage your nodes that aren't
behind NATs for rendezvous, UDP hole punching, and falling back to plain
forwarding as necessary. There is no need to forward any ports, and the
latency will be pretty much unaffected.
