You may be prompted to restart the BSC. We recommend that you do not restart the BSC
until you have completely finished configuring the BSC for use in your network.
Domain Name System (DNS) Settings
The BSC DNS settings serves these main purposes:
•
DNS Proxy - By default, wireless clients can see and access any DNS server
addresses configured on the protected interface. Enabling DNS Proxy overrides the
DNS information provided to the wireless clients with the IP address of the BSC's
managed interface and receives and forwards all DNS requests as appropriate.
•
Answer failed DNS queries - Enabling this option means the BSC answers all DNS
requests for any user who is not logged into the network. If a user enters a valid DNS
name or URL, the BSC serves the user login page and then redirects the user to his
requested destination after he has logged into the network. If a user enters an invalid
DNS name or URL, the BSC serves the user login page and then displays the
appropriate warnings/errors after the user has logged into the network. Enabling this
option allows the BSC to redirect a higher percentage of users trying to access the
network.
•
Redirection and local resolution of DNS requests - For access to certain BSC
functions, such as user login, logout, administrator login, and secure tunneling
protocols (IPSec, L2TP/IPSec, and PPTP), you can specify a single DNS address for
each hostname that maps to that function. The BSC forwards each DNS request to the
specified managed or protected interface for name resolution. This is particularly
useful when configuring secure tunnel endpoints in large multi-BSC networks. You
only need to maintain a single DNS entry for each endpoint instead of tracking and
configuring the endpoint's IP address for each BSC in the network.
