DHCP Popup message

[gbwatkins]

Hey, I have a public network connection supplying DHCP via the router over wirelss to a cafe in town. I want to post a pop up message of sorts with a legal disclaimer upon the client machine receiving an address. I would also be willing to force a http redirect to a webpage on my site containing this disclaimer. Does anyone know if the router can perform either of these functions and if so then how do I configure?

Thanks for any and all responses.

there was a software/appliance from cisco dedicated for that called Cisco Building Broadband Service Manager. unfortunally it is end of sale

but in the link above they say Cisco NAC Appliance is the replacement. i am not sure if it has same features as BBSM.

So, is there no way for the router to provide this message or http redirect? I am looking for something similar to the popup when you terminate a vpn tunnel.
