A filter to block NetBIOS packets
•
Introduction
The NETBIOS protocol allows the sharing of Microsoft computers in a workgroup. For security reasons, the
Prestige blocks NetBIOS connections from the outside by default. To enable the NetBIOS service, remove the
filter sets applied in SMT menus 3.1 and 4.1. The details of the filter settings are described as follows.
•
Configuration
The following lists the packets that are blocked. Configure the rules in the filter set in SMT menu 21.
Filter Set 1:
o
Rule 1-Destination port number 137 with protocol number 6 (TCP)
o
Rule 2-Destination port number 137 with protocol number 17 (UDP)
