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:

Block or forward NetBIOS packets from being sent from the LAN to the WAN.

Block or forward NetBIOS packets from being sent from the WAN to the LAN.

Allow or deny NetBIOS packets to be sent through VPN connections.
