Authentication-Free User And Free Ip Address Configuration - 3Com 3C13636 Configuration Manual

3Com Router 3000 Ethernet Family
Configuration Guide
Note:
The following describes only the configurations related to re-DHCP authentication.
For configurations of the RADIUS scheme and ISP domain, refer to section 3.2.3
"Direct Authentication Configuration Example".
For re-DHCP authentication, the DHCP server must support portal authentication,
and you must create both a public address pool and a private address pool, which
are 172.21.0.0/16 and 18.21.0.0/16 respectively. The detailed configurations are
not described here.
For re-DHCP authentication, you must configure the router as a DHCP relay instead
of a DHCP server, and configure the portal-enabled interface with a primary IP
address and a secondary IP address for use on public and private networks
respectively.
