mapping client networks to work with ECS

[George (Yorgos) Thessalonikefs]

Hi Antonio,

This is not possible.

If you control the clients you can have them include an ECS option with 
the desired network and Unbound will use that.

My next bet would be NATing so that Unbound sees the fake client IP.
