I am researching for a project specification and I would like to know if it is possible to get the MAC address of a client machine connected to a Cisco router and then inject that address into any HTTP traffic that the controller sends to a proxy.
The basic overview of the architecture and what I want is client connects to router, router connects to controller and controller connects to proxy. I want the controller to basically know which client MAC addresses are connected to the router and what they are viewing.
