A DNS whitelist is used in conjunction
with a captive portal to provide captive portal services to wireless clients. Use the
DNS whitelist parameter to create a set of allowed destination IP addresses within the
captive portal. These allowed IP addresses are called the Whitelist. To effectively host
captive portal pages on an external Web server, the IP address of the destination Web
server(s) should be in the whitelist.
To define a DNS whitelist:
Procedure

whitelist, Edit to modify a selected whitelist, or Delete to remove

To create a whitelist, assign it
a name up to 32 characters.

to populate the whitelist table with Host and IP Index parameters that must be
defined for each whitelist entry.
