=== NAT all inside the mesh ===
How do you hve rts set on your cpe? If its not set to 250 to match the 
meshnode then one hidden node client can jam up all the avalbe wireless 
airtime regardlss of how you set the bandidth shaping. This coud be 
what you 
are seeing.

to use Mikrotik as my radius and traffic shaping part of my mesh.
