192.168.1/24 is not a valid netmask -> - is not a valid netmask -> -

honestly go to and test what your proposed 
netmasks are doing

hint: using /24 everywhere is nonsense and what you are trying here (if 
it's accepted at all) is do allow and deny the actly same range by lack 
of understanding how network masks are working
