Allow flexible control of file and printer sharing

If you want more flexible control of file and printer sharing on your networks (for example, uni-directional NetBIOS traffic), you can do the following:

  1. Allow file and printer sharing on other LANs (Local Area Networks) than those in the LAN settings list. This allows NetBIOS traffic on those LANs to be processed by the firewall rules.
  2. Create high-priority global rules which allow communication to/from hosts with the appropriate NetBIOS ports and protocols. We recommend that you create global rules to explicitly block all unwanted file and printer sharing traffic rather than let it be handled by the default rule.

To allow file and printer sharing on other LANs than those in the LAN settings list:

  1. On the Home page, under Firewall, click Configure firewall.
    For information about the Home page, see About the Home page.
  2. Under Configurations, click Configure next to the location that you want to configure.
  3. On the LAN tab, clear the Block file and printer sharing for other networks check box.
