A DNS whitelist is used in conjunction
with a captive portal to provide access services to wireless clients. Use the whitelist
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) should be in the whitelist.
To define the whitelist:
Procedure
Go to Configuration → Services.
The upper, left-hand,
side of the user interface displays a Services menu pane where Captive Portal,
DHCP and RADIUS configuration options can be selected.
Expand the Captive Portals
node and select DNS Whitelist.
The DNS Whitelist screen displays.
Review the names of existing whitelists. Click Add to
create a new whitelist entry, or select an existing whitelist and click
Edit to modify it.
