NetBIOS over TCP/IP Filter

The Protocols Filter control lets you list the TCP port numbers for up to sixteen protocols that you do not want LAN users to use over the WAN connection. A list of standard, commonly used TCP port numbers appears next to the table to help you create entries. To create an entry, simply click in a TCP Port # box and type a port number.

NetBIOS is a communication protocol designed for use on small networks and heavily reliant on network-wide broadcasts. “NetBIOS over TCP/IP” (often abbreviated as NBT) is a means of letting NetBIOS requests travel between networks in TCP/IP packets. This method is used in Windows 95 and Windows NT.

Since NetBIOS over TCP/IP can be routed between networks, it can trigger dial-out on a dial-on-demand PPPoE WAN connection (see “Global WAN Mode” under “Basic Setup — Broadband Router,” above). If you have a PPPoE link to your ISP, and the Connect on Demand control is set to Yes, you will almost certainly need to enable the NetBIOS over TCP/IP filter. When the filter is enabled, NetBIOS over TCP/IP packets will not trigger dialing and will not be passed from the LAN to the WAN link. (NetBIOS over TCP/IP will still work among the machines on the LAN.)

If the Wireless Gateway's WAN port connects a LAN to a corporate network containing resources that local machines must access using NetBIOS over TCP/IP, the NetBIOS over TCP/IP Filter control should be set to Disable to let those packets through.

Block WAN Request

The Block WAN Request function, if enabled, causes the Wireless Gateway to ignore requests addressed to it from the WAN. This makes the Wireless Gateway almost “invisible” to the outside world while still allowing access to the WAN from the LAN.

Note that if the Block WAN Request function is enabled, outside machines will not be able to “ping” the Wireless Gateway and remote management of the Wireless Gateway will not be possible.
