IP addresses are recorded in the CIDR notation, which allows the following
variations:
• aaa.bbb.ccc.ddd – a specific IP address, for example, 192.168.0.17;
• aaa.bbb.ccc.ddd/mm – subnet address with a specified number and
mask, for example, 192.168.0.0/16.
Addresses in lists can be delimited by spaces, line feed symbols, commas or
semicolons.
4.3.3. Managing the lists of employed
DNSBL services
Use the DNS Black Lists link in the Common menu of the Policies section (see
Fig. 11) to open the page where you can manage the lists of DNSBL services.
Configuration of the list of DNSBL being used applies to the default filtration
policy. Later you can specify for every user group whether it should use the
results of DNSBL-based checks. The list of employed services is common for all
user groups.
Figure 11. Configuration page for the lists of DNSBL services
The central part of the page displays a list of used services. For every DNSBL
service you will have to specify the address used to access that server and its
rating.
