Configuring cross-subnet portal authentication with extended
functions
Network requirements
As shown in Figure 60, configure Router A to perform extended cross-subnet portal authentication for
users on the host. If a user fails security check after passing identity authentication, the user can access
only subnet 192.168.0.0/24. After passing the security check, the user can access Internet resources.
A RADIUS server serves as the authentication/authorization server.

Configuration prerequisites and guidelines
• Configure IP addresses for the host, routers, and servers as shown in Figure 60 and make sure that
routes are available between devices.
• Configure the RADIUS server properly to provide authentication and authorization functions for
users.
