+          NetBIOS name service requests are sent as broadcast messages from an
+          unprivileged port and responded to with unicast messages to the
+          same port. This make them hard to firewall properly because connection
+          tracking doesn't deal with broadcasts. This helper tracks locally
+          originating NetBIOS name service requests and the corresponding
+          responses. It relies on correct IP address configuration, specifically
+          netmask and broadcast address. When properly configured, the output
+          of "ip address show" should look similar to this:
+
+          $ ip -4 address show eth0
