Portal ReDHCP
Authentication Method
Configuration Example
Network requirements
■ Portal is enabled on the switch and Portal runs in the ReDHCP authentication
method.
■ Configure address pools on the DHCP server: 172.21.0.0/16 for public
networks and 18.21.0.0/16 for private networks.
■ The user was assigned a private address before passing Portal authentication.
The user can access the external networks only after the user applies for a
public address after passing Portal authentication.
