I have a Fortinet FortiGate firewall, a Dell PowerConnect switch and will be getting a Comcast router for Internet access at a business. Basically, this is a new network to be installed in parallel with a functional network from another provider. Once the new network is stable, the old network will be retired. The reasons for this are that the present network is wireless access only with the router located in the office instead of the telephone closet, and we are adding a file server which does not have wireless access, a few extra computers, the switch, and the hardware firewall. Right now the wireless router is acting as the DHCP server. However, I do not think it will work properly from the telephone closet given the wiring in there. From what I have gathered so far, each of the three units in question can function as a DHCP server: my question is which is the best choice? My idea for the network is the computers, wireless access point, and server being plugged into wall jacks which lead to the telephone closet where the PowerConnect switch will be, which itself will be plugged into the Fortinet, which will be plugged into the Comcast router, which will connect to the Internet. It seems to me that the switch should be the DHCP server but that implementation seems to be rather complex. Any suggestions would be greatly appreciated.
