The easiest option in your situation is (assuming your switch has the
capability) probably to have the switch insert a "agent.circuit-id"
option into the DHCP requests. You can then use the option to define a
class based on which-ever switch port your AP connects to and limit the
address pool to that class. Only clients connecting through the AP will
get a dynamic address. A separate VLAN and subnet is definitely cleaner
but it should not be required if you cannot live with a layer 3 split.
Configuring the DHCP server is relatively straight forward. Setting
up the switch is an exercise for the reader.
