I did this in the hosts file in office-1, but it has no effect. Maybe it 
is overwritten when the real config from man-in-the-middle is known?

Setting this Subnet and its Weight in the hosts file on the 
man-in-the-middle doesn't work. The routing then seems to be messed up 
and it
would be wrong anyway to tell all nodes to route office-1, office-2 via 
that man-in-the-middle. This should be done for the connection between
office-1 and office-2 only.
