R3303-HP HSR6800 Routers Security Configuration Guide

147
Configuration prerequisites and guidelines
• Configure IP addresses for the router and servers as shown in Figure 56 and make sure the host,
router, and servers can reach each other.
• Configure the RADIUS server properly to provide authentication and authorization functions for
users.
• For re-DHCP portal authentication, configure a public address pool (20.20.20.0/24, in this
example) and a private address pool (10.0.0.0/24, in this example) 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 of
the interface connecting users (20.20.20.1 in this example), the private IP address range for the IP
address group associated with the portal device is the private network segment where the users
reside (10.0.0.0/24 in this example), and the public IP address range for the IP address group is
the public network segment 20.20.20.0/24.
Configuration procedure
1. Configure a RADIUS scheme:
# Create a RADIUS scheme named rs1, and enter its view.
<Router> system-view
[Router] radius scheme rs1
# Set the server type for the RADIUS scheme. When using the IMC server, set the server type to
extended.
[Router-radius-rs1] server-type extended
# Specify the primary authentication/authorization server, and configure the keys for
communication with the servers.
[Router-radius-rs1] primary authentication 192.168.0.113
[Router-radius-rs1] key authentication radius
# Specify that the ISP domain name should not be included in the username sent to the RADIUS
server.
[Router-radius-rs1] user-name-format without-domain
[Router-radius-rs1] quit
2. Configure an authentication domain:
# Create an ISP domain named dm1 and enter its view.
[Router] domain dm1
# Configure AAA methods for the ISP domain.
[Router-isp-dm1] authentication portal radius-scheme rs1
[Router-isp-dm1] authorization portal radius-scheme rs1
[Router-isp-dm1] quit
# Configure domain dm1 as the default ISP domain for all users. Then, if a user enters a username
without any ISP domain at logon, the authentication/authorization methods of the default domain
are used for the user.
[Router] domain default enable dm1
3. Configure portal authentication:
