The dhcp can allot IP if the request comes to dhcp, if the user changes to fixed IP then dhcp does not have any role to play.
I have done similar thing but for the squid. 1. All the traffic coming from local LAN is transferred to a daemon (port 80) using IP tables. 2. The daemon puts up a login screen to user. The user (on win machine) enters a username/password. 3. If the user name and password are correct, the entry in IP tables is removed, and user can browse through proxy only. You may similar thing.
