only 200 user can connect with DMA radius manager !

Hi…

I have DMA radius manager 3.9 license to 5000 users ( now I have 1200 users )
I connect it with MT 5.7 ..
I create a pool like this : 44.55.0.4-44.55.15.254
& the users can connect & take ips like : 44.55.15.253, 44.55.15.252 … 44.55.14.253 & so on
but only 200 users can connect at the same time !!
can any one help me to solve the problem ..

thx.
