Configuring Extended Re-Dhcp Portal Authentication - HP VSR1000 Security Configuration Manual

Configuring extended re-DHCP portal authentication

Network requirements
As shown in
IP address through the DHCP server. A portal server serves as both a portal authentication server and a
portal Web server. A RADIUS server serves as the authentication/accounting server.
Configure extended re-DHCP portal authentication. Before passing portal authentication, the host is
assigned a private IP address. After passing portal identity authentication, the host obtains a public IP
address and accepts security check. If the host fails the security check, it can access only subnet
192.168.0.0/24. After passing the security check, the host can access Internet resources.

Configuration prerequisites and guidelines
Configure IP addresses for the router and servers as shown in
•
router, and servers can reach each other.
• Configure the RADIUS server correctly to provide authentication and accounting functions.
For re-DHCP portal authentication, configure a public address pool (20.20.20.0/24) and a private
•
address pool (10.0.0.0/24) on the DHCP server. (Details not shown.)
For re-DHCP portal authentication, the router must be configured as a DHCP relay agent and the
•
portal-enabled interface must be configured with a primary IP address (a public IP address) and a
secondary IP address (a private IP address). For information about DHCP relay agent configuration,
see Layer 3—IP Services Configuration Guide.
Make sure the IP address of the portal device added on the portal server is the public IP address
•
(20.20.20.1) of the router's interface connecting the host. The private IP address range for the IP
address group associated with the portal device is the private subnet 10.0.0.0/24 where the host
resides. The public IP address range for the IP address group is the public subnet 20.20.20.0/24.
Configuration procedure
Perform the following configurations on the router.
1. Configure a RADIUS scheme:
# Create a RADIUS scheme named rs1 and enter its view.
