In its proxy function, the unit answers queries to computers already known in the
NetBIOS module (on the billboard) by proxy for those computers. After the initial
exchange of information, no new connections are established as a result of queries
to workstations in the local network, or to known workstations in the remote
network.
The preset IP filter for NetBIOS ports intercepts packets with queries for stations not
present in either the LAN, or as established NetBIOS remote stations, thus preventing the
establishment of a connection via the DEFAULT route to the Internet.
Which preconditions must be fulfilled?
A number of components must be installed on the participating workstations and a
variety of settings made in the operating system to ensure correct communications via
routers for the interconnection of Microsoft Networks.
Installed components
The installation of the required components will be illustrated here on the basis of
Windows 95 or Windows 98; the procedure for Windows NT 4.0 is similar. Install the
following components on all workstations in the Microsoft Networks to be
interconnected:

Network protocol
NetBIOS is completely independent of the transport protocol used. NetBIOS
network data can thus be transferred using the NetBEUI (NetBIOS Extended User
Interface), IPX (Internet Packet eXchange, Novell) or IP (Internet Protocol) protocols.
Unlike IPX and IP, NetBEUI is not routable and is thus only available in Microsoft
Networks. If multiple Microsoft Networks are to be interconnected using routers,
NetBIOS must be based on a routable protocol in the ELSA LANCOM Wireless, such as
IP.
The routing of NetBIOS packets in the ELSA LANCOM Wireless is based on TCP/IP
due to its superior filter mechanisms. This protocol must therefore be installed on
all participating workstations.
