Using Quick Internet Connection/Disconnection Using Quick Internet Connection/Disconnection By clicking the Connect or Disconnect button (depending on the connection status) on the Internet page, you can establish a quick Internet connection using the currently selected connection type. In the same manner, you can terminate the active connection. The Internet connection retains its Connected/Not Connected status until the NetDefend firewall is rebooted. The NetDefend firewall then connects to the Internet if the connection is enabled. For information on enabling an Internet connection, see Enabling/Disabling the Internet Connection on page 88. Configuring a Backup Internet Connection You can configure both a primary and a secondary Internet connection. The secondary connection acts as a backup, so that if the primary connection fails, the NetDefend firewall remains connected to the Internet. Note: You can configure different DNS servers for the primary and secondary connections. The NetDefend firewall acts as a DNS relay and routes requests from computers within the network to the appropriate DNS server for the active Internet connection. 90 D-Link NetDefend firewall User Guide
