Appendix C Netbios Filter Commands - ZyXEL Communications P-324 User Manual

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:
•
Allow or disallow the sending of NetBIOS packets from the LAN to the WAN and from the WAN
to the LAN.
•
Allow or deny NetBIOS packets to be sent through VPN connections.
•
Block or forward NetBIOS packets from initiating calls.
