We have nat on our "uplink" router, connected to mesh nodes via
wireless back hauls.  This nat router provides a /16 network.  It will
perform ESFQ, which is an easy way to limit bandwidth to every ip
address in the /16.  I want the mesh nodes to each run wifidog,
passing the traffic along as a router, so that the main "uplink" nat
router can limit all of the users to a fair amount of bandwidth.

If the mesh nodes were each running their own nat, then ESFQ would be
needed on each node and the result would be very much less nice than
the first paragraph.  Like having lumps in your pancakes.  Or crepes.

Thank you for the jpg, it's a lot easier to read than iptables -L...
