The “No restrictions” column reflects the default configuration (see also the screenshots). That is,

IP Access Filter
Allows defining a range of trusted IP addresses that are allowed to access Damocles2 over
HTTP and SNMP. The IP range is configured separately for each protocol.
To set up the filter, specify the base IP address and the mask that define the trusted range ac-
cording to the formula below (AND is bitwise multiplication). Access is granted if the condition
is true.
( IP trying to access AND Mask Value ) = IP Address Value
Security
Security settings. Restrictions in individual modes are shown in the following table. Lines indi-
cate the method of accessing the device over IP, columns specify the restrictions resulting from
the respective security settings.
