Finally, use the filter list to specify the users that cannot access certain names or

domains.

cd setup/dns-module/filter-list

set 001 www.offlimits-domain.com 0.0.0.0 0.0.0.0

This entry (with the index '001') prohibits this domain for all of the computers in the

local network. The index '001' was selected freely and is only intended to enhance

the overview. The wildcards '?' (stands for exactly one character) and '*' (for a

random number of characters) are valid when entering the domain. For example, if

only a single computer (IP 10.0.0.123) is to be prohibited from accessing DE-

domains, enter:

set 002 *.de 10.0.0.123 255.255.255.255

The hit list in the DNS statistics contains the 64 most frequently requested names and

provides a good basis for setting up the filter list.

If your LAN uses subnetting, you can also apply filters to individual departments by

carefully selecting the IP addresses and subnet masks. The IP address '0.0.0.0'

stands for all computers in the network, and the subnet mask '0.0.0.0' for all

networks.

NetBIOS proxy

With the NetBIOS proxy function, a

ELSA LANCOM Wireless

can also route NetBIOS

packets or respond locally as a proxy. As a result, it is now possible to economically link

Microsoft Networks using the router function.

This section describes the general functions of NetBIOS proxy, as well as the

configuration of the router and workstations for the interconnection of Microsoft

Networks.

To the point: What is NetBIOS?

NetBIOS provides a simple, trouble-free means of networking multiple computers. An

important example for NetBIOS networks is the Microsoft Network, with which several

Windows 3.11, 9x and NT workstations can be networked simply by sharing the

resources (drives or printers) of the individual computers with the other participants.
