The following describes the NetBIOS packet filter commands.

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 do the following:
• Allow or disallow the sending of NetBIOS packets from the LAN to the WAN and from
the WAN to the LAN.
• Allow or disallow the sending of NetBIOS packets from the LAN to the DMZ and from
the DMZ to the LAN.
• Allow or disallow the sending of NetBIOS packets from the WAN to the DMZ and from
the DMZ to the WAN.
• Allow or disallow the sending of NetBIOS packets through VPN connections.
• Allow or disallow NetBIOS packets to initiate calls.
