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:
-
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.
-
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.
