NetBIOS Filter Commands

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 do the following (filters for DMZ are not available on all models):

• Allow or disallow the sending of NetBIOS packets from the LAN to the WAN.

• Allow or disallow the sending of NetBIOS packets from the WAN to the LAN.

• Allow or disallow the sending of NetBIOS packets from the LAN to the DMZ.

• Allow or disallow the sending of NetBIOS packets from the WAN to the DMZ.

• Allow or disallow the sending of NetBIOS packets from the DMZ to the LAN.

• Allow or disallow the sending of NetBIOS packets 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.
