Yes, it should be fine.  You just have to protect lwIP from having
multiple threads active in the stack at the same time using (for
example) a mutex.  I'm not sure to what extent lwIP has been integrated
into freertos - this may have been done for you already at the sockets
layer, assuming that is the API you wish to use.

Is there someone else here using freertos with lwIP who can provide more
concrete information on its capabilities?
