Configuring Re-DHCP Portal Authentication
Network requirements
As shown in
z
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 the user can access Internet
resources.
z
A RADIUS server serves as the authentication/accounting server.
