A DNS whitelist policy is used in
conjunction with a captive portal to provide access services to wireless clients. Use
the whitelist policy to create a set of allowed destination IP addresses within the
captive portal. To effectively host hotspot pages on an external Web server, the IP
address of the destination Web server(s) must be in the whitelist.To configure the
whitelist:
-

The DNS Whitelist
window opens. If any whitelist policies are configured, they appear in a list in
the DNS Whitelist pane. The total number of configured whitelist policies is
shown in parentheses. You can choose from the following actions:
-
Select the sort icon
adjacent to a column heading to sort the data by the heading topic. By default,
the data is sorted in ascending order, as indicated by the direction of the
arrow in the icon
. Toggle the icon to sort the column data in
descending order
. The "1" indicates by which column heading topic
the data is currently sorted.
