The prerequisite of Portal authentication-free user and free IP address 
configuration-the basic Portal configuration has been finished.

Portal authentication-free user and free IP address configuration is optional. The 
following table describes its configuration procedure:

c 

■

The ReDHCP authentication method requires that the IP address of an 
authentication-free user and the master IP address of the interface belong to 
the same network segment. The Direct authentication method requires that 
the IP address of an authentication-free user and that of the VLAN interface 
belong to the same network segment.

■

This configuration takes effect after Portal is enabled in the VLAN that the 
authentication-free users belongs to.

■

The Layer 3 Portal authentication method does not support the 
authentication-free user configuration.

■

Portal is enabled on the switch and Portal runs in the Direct authentication 
method.

■

The user can access the internal server Server1 before passing Portal 
authentication.
