[Babel-users] not routing

Oh, I see.

Basically, you've got the following topology:

    === A ... B ... C ---

where === and --- are external (wired) routes, and ... are wireless
links controlled by Babel.

Now what you can easily do is select which route B will prefer, since
B's routing tables are under the control of Babel.  What is more
difficult is controlling which route will be taken by C, since the route
taken by C is under control of an external agent (DHCP, Babel, whatever).

I really don't see a good solution that doesn't require modifying the
DHCP server on C.  A workaround would be to move C into the Babel
network by adding a new node C':

   ==== A ... B ... C . C' ---

where C' routes through the slow ADSL line, and C chooses between B and
C' using Babel.
