address pools are listed. The entries are saved and you have defined an

7.1.5 Setting Filters
NetBIOS filters If you are working with Windows in your local network, you should set
➤➤
NetBIOS filters to save costs. This prevents establishing connections
from the network to your Internet Service Provider (
➤➤
ISP ), e.g. in order to
forward WINS requests from PCs in your network. This means that X4000 asks
your ISP which
➤➤
host name can be assigned an IP address. These
connections are unnecessary because the ISP cannot resolve WINS names,
but still cost money.
A more detailed explanation of
➤➤
filters and security can be found in
chapter 10.2.8, page 335 .
To do To prevent these unnecessary connections, proceed as follows:
You can also create several entries to define an IP address pool of
unconnected address ranges, e.g. 192.168.1.20 - 192.168.1.29 and
192.168.1.35 - 192.168.1.40, and so on.
When configuring filters, make sure not to lock yourself out.
➤
Use the serial interface or ISDN login on X4000 for filter configuration.
➤
If you still access X4000 over your LAN (e.g. telnet), before starting filter
configuration select in the menu
