I've setup a DHCP server but I need to setup a web based authentication for the same.
I have a webserver running on the same box. Once the client machine receives an IP address served from the DHCP server, how can I pop up a web page with authentication on it?
Only if the user authenticates and stays logged on should he have internet access from that machine. Once he closes that window or logs off, his IP address should be released.
Thanks in advance for your help.
