about your questions, there's only one PC which is the windows server PC behind the mid-router between the windows server and the ISP router, then the cliens those would connect to the windows server (the end users) may reach up to 200 - 250 client.

and i am using the third DHCP server (windows server) to control bandwith and also to have multi roles , 3 roles for each group.
