5.1.7 Setting Filters
NetBIOS filters If you are working with Windows in your local network, you should set
➤➤
NetBIOS filters in order to reduce charges. This prevents X3200 setting
up connections, e.g. to the Internet Service Provider (
➤➤
ISP ), in order to for-
ward WINS requests from PCs in your network. That is, X3200 asks the ISP
which
➤➤
host name can be assigned to an IP address. These connections
are unnecessary because the ISP cannot resolve WINS names, but still cost
money.
A more detailed explanation of
➤➤
filters can be found in chapter 7.2.8,
page 286 .
To prevent these unnecessary connections, proceed as follows:

nected address ranges, e.g.
192.168.1.20 - 192.168.1.29 and 192.168.1.35 -
192.168.1.40
, etc.
