 Your subnet masks look like one part of the problem.

 112 = 0111 0000

  Subnet masks require continous bits of 1

  Since you are dividing the nets into 32 addresses each or 8 
  subnets, 

  111 00000 = 224

  So try 255.255.255.224

  Also, the RFC isn't clear on this and most routers ignore this anyway
  (ie. you can get away with it) but you shouldn't use the 0 or 8 subnets.
