ISP security

Hello, I have a network armed with camopy and it wanted to be ISP. But I have some doubts with regard to the safety that the Canopy provides to my network. In my central site I have a server with dhcp in that this one installed the BAM. In the same site I have 6 APs, with the certificate for APAS. I have near 10 SM installed. I ask you. Since I realize the validation of the network, to be able to give to my clients, a dynamic ip address in his PC, and as that the same one is not going to change happiness ip into similar other one without creating conflict with my dhcp. If someone is experienced as ISP with a Canopy network would be grateful for his commentaries.
