DHCP MAC Filtering

DustyMiller · 15 Dec 2009 at 15:30

My boss wants our DHCP server currently Server 2003 R2 to be able to give different IP and options depending on the MAC address of the client.

so Windows PC's are forced via the ISA server, and things like smartphones, and their lack of a ISA firewall client, and proxy settings go straight out via a different gateway.

Is this possible, I know using the DHCP callout i can block or allow by MAC address, but this applies to all addresses issued by the server thus I cannot control to the level I need.

Any ideas ??

I currently only have one active DHCP server. I guess the other way is to have multiple DHCP server each allowing only their own set of MAC addresses, this would require 4 DHCP servers. one for Dekstops & guests, one for Smartphones, and a second set for failover. And it's not very pretty either.

Damn you DHCP system. It doesnot help only having one subnet either.

HHHHmmmm I wonder if my Cisco switches & AP's can help ????

vlans wont work for us, as we have wireless barcode scanners, along with the new smartphones.

But The VLAN's & multiple SSID's dont get me around the main problem, which is multiple different DHCP servers on a single subneted network, or have I missed something here ?

All of our Cisco switches are 3560's. But how can I seperate smartphones and wirteless barcode scanners, and thus laptops from the access points they all connect to.
