NetBIOS filter commands
The following describes the NetBIOS packet filter commands.
Introduction
NetBIOS (Network Basic Input/Output System) are TCP or UDP packets that
enable a computer to connect to and communicate with a LAN.
For some dial-up services, such as PPPoE or PPPoA, 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.
