Configuring Re-DHCP Portal Authentication

Network requirements
The host is directly connected to the switch and the switch is configured for re-DHCP
authentication. The host is assigned with an IP address through the DHCP server. Before portal
authentication, the host uses an assigned private IP address. After passing portal authentication, it
can get a public IP address and then users using the host can access unrestricted Internet
resources.
A RADIUS server serves as the authentication/accounting server.
