Configuration prerequisites and guidelines
•
Configure IP addresses for the router and servers as shown in
host, 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.
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.
•
If you have configured a preauthentication IP address pool on portal-enabled interfaces,
configure a DHCP relay address pool with the same name on the device. For the DHCP relay
address pool, specify the subnet address the unauthenticated users reside (with the
export-router keyword specified) and the DHCP server address.
Configuration procedure
Perform the following tasks on the router.
1. Configure a preauthentication domain:
# Create an ISP domain named abc and enter its view.
<Router> system-view
[Router] domain abc
# Specify authorization ACL 3010 in the domain.
[Router-isp-abc] authorization-attribute acl 3010
[Router-isp-abc] quit
# Configure a rule to permit access to the subnet 192.168.0.0/24.
[Router] acl advanced 3010
