Allow all traffic on a LAN

To allow all traffic between computers on a LAN (Local Area Network):

  1. On the Home page, under Firewall, click Configure firewall.

    For information about the Home page, see About the Home page.

  2. On the LAN tab, do one of the following:
    • Click Detect LAN to detect the LAN that your computer is on and add it to the list of network addresses.
    • Click Add. In the Select address dialog box, select the Address format, type the domain name or IP address, and then click Add.
      Note If you select Local network (detected automatically), you do not need to type anything. This option is not available on Windows 8 and later. For information about local network detection, see About local network detection.
  3. Click OK to close the Select Address dialog box.
  4. In the LAN settings list, select the Trusted check box for a network.


  • If you allow all traffic between the computers on a LAN, you also allow file and printer sharing on it.
