Wireless LAN with multiple SSID how to allocate network address using centralised DHCP

I am looking to extend a wireless network from 2 access points to 8 access points. The current access points have separate SSID so that they can connect to two separate networks The requirement is to now replicate the functionality with 6 access points each capable of supprting mutiple SSID. Each SSID will be associated with a VLAN so that I get the effective separation of the two networks. The current arrangement works by the fact that one network is relatively open and just has a preshared key that the students know so that they can access their email etc. The other network has a preshared key and MAC address filtering so that staff can gain access to the office network I am trying to figure out how to do network address information using microsoft DHCP so that if I reserve an address based on MAC address that device will end up on the secure network otherwise they will end up on the student 'open' network. I know there are systems to control acess points that provide a mangement interface from teh likes of Cisco and Aruba. The school can't afford these and wishes to use a lower cost device such as the tp-link equipment http://www.tp-link.com/products/productDetails.asp?class=wlan&pmodel=TL-WA901ND.

Software/Hardware used:
tp-link wa901

Your project sounds like a perfect match for <a href=”http://meraki.com”>Meraki</a> (who are the guys who pay my bills). I’m no salesman, but I’m told we’re typically half the cost of Cisco and I know for sure that multiple SSIDs and VLANs are not a problem.

    I am a bit unsure what advice it is you need. If you are already using 2 WAPs with security filtering why can you not extend the system you have running now? You do not say what router you are using for the current system, and my first thought is how are you going to connect 8 WAPs to your router. 8 rj45 connectors need 8 sockets. Are you using a managed switch for the VLANs? What system of filtering are you using now? DHCP is used to allocate an IP address to a device. DHCP is not used to routefilter user information. That is done by an ACL (Access Control List) on the router/managed switch. An Access Control List refers to rules that are applied to port numbers or network daemon names that are available on a host or other layer 3, each with a list of hosts and/or networks permitted to use the service. Both individual servers as well as routers can have network ACLs. Access control lists can generally be configured to control both inbound and outbound traffic, and in this context they are similar to firewalls. So if you have a list of static IPs linked to MAC addresses you can allow or deny access to servers etc. It sound like you have this already set up.
