Configuration procedure
In re-DHCP authentication mode, you must configure a public IP address pool
■
(for example, 20.20.20.0/24) and a private IP address pool (for example,
10.0.0.0/24) on the DHCP server. For detailed configuration about DHCP, refer
to "DHCP Overview" on page
In re-DHCP authentication mode, the access device must be configured as a
■
DHCP relay agent (instead of a DHCP server) 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).
IP addresses are configured for devices as required and routes are available
■
between devices before the portal+ feature is enabled.
The following only describes the configurations related to the portal+ re-DHCP
■
authentication mode. For configurations about the RADIUS scheme and ISP
domain, refer to
page 1865.
Configure the access device:
# Configure the portal+ server as follows:
Name: newpt
■
IP address: 192.168.0.111
■
Key: portal
■
Port number: 50100
■
URL: http://192.168.0.111/portal.
