Features of the filter of the
product
Static filter and dynamic filter
The following two types of filters can be configured in the
product. Use advantages of each type together to configure
your settings.
Static filter: Once this filter has been configured, it is
•
constantly enabled irrespective of presence of data or
communication.
• Dynamic filter: This filter monitors the communication
status and is enabled on an as-needed basis. For example,
you can configure a setting such as "normally prohibiting
all data from the Internet to LAN, but permitting only
when an access from LAN to ftp occurs".
When a connection destination is
registered in "Basic configuration
page", the basic filter is applied
Only by registering a connection destination with "Basic
configuration page", the following filter is automatically
applied according to the connection type. In addition to
this basic filter, you can add, register, and apply filters if
necessary.
Note
• Security levels and settings are subject to change without
notice.
• If you specify a connection destination using the console, no
filter is registered.
For provider configuration
Seven security levels are defined as filter combination
patterns. When a new provider is registered, the security
level 6 settings are automatically applied. The security level
can be changed at a later time if necessary. (page 96)
Filter number indication
You can use almost unlimited filter function numbers of the
product. In "Basic configuration page", up to 100 numbers
(0 to 99) can be set for each destination. The following
shows the correspondence between areas and filter numbers
used in "Basic configuration page".

Note
• Before changing a filter setting, you should fully understand
the function to assure security.
• Applying too many filters may complicate the processing,
causing the Internet access speed to be slow.
