Firewall

It is recommended that you use a firewall to secure your local network from unauthorized Internet access.

Important

  • If you do not enable the firewall on your server, you must configure a firewall device to protect your local network from unauthorized access. For more information about the firewall settings to configure for your local network, see Appendix C, "Network Configuration Settings," of Getting Started.
  • You might encounter an error if you use the options on the Firewall Configuration page of the Configure E-mail and Internet Connection Wizard to configure a UPnP™ firewall/router device.
    To try to resolve this issue, go to the Web site of the device manufacturer to download and install the latest firmware update. To download and install the latest firmware update for Microsoft base stations, see the Microsoft Broadband Networking Web site at http://go.microsoft.com/fwlink/?LinkID=18588. After you install the firmware update, rerun the Configure E-mail and Internet Connection Wizard and try to configure the device.
    If the problem persists, you must manually configure the device by using the settings documented in Appendix C, "Network Configuration Settings," of Getting Started.
