The following describes the NetBIOS packet filter commands. See the Command Interpreter appendix for
information on the command structure.
Introduction
NetBIOS (Network Basic Input/Output System) are TCP or UDP broadcast packets that enable a computer to
connect to and communicate with a LAN.
For some dial-up services such as PPPoE or PPTP, NetBIOS packets cause unwanted calls.
You can configure NetBIOS filters to:
•
Block NetBIOS packets from being sent from the LAN to the WAN.
•
Block NetBIOS packets from being sent from the LAN to the DMZ.
•
Allow NetBIOS packets to be sent through VPN connections.
•
Block NetBIOS packets from initiating calls.
