Appendix D
NetBIOS Filter Commands
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 through VPN connections.
• Allow or disallow NetBIOS packets to initiate calls.
