2d. IP/Mask
Specifies the IP address or IP-address range for which the rule applies. In
the following examples, the number concatenated to an IP address with
a " / " represents the number of valid bits of the given IP address that will
be used.
192.168.1.22/32 matches the IP address 192.168.1.22
192.168.1.0/24 matches all IP packets with source addresses from
192.168.1.0 to 192.168.1.255
0.0.0.0/0 matches any IP packet
2e. Policy
The policy determines what to do with matching packets. They can be
either accepted or dropped.
Warning: The order of the rules is important. The rules are checked
in ascending order until a rule matches. All the rules below the
matching one will be ignored. The default policy applies if no match
has been found.

2g. Inserting a Rule

3. User Blocking
The user-blocking mechanism allows the administrator to disable the login of a
certain user if his or her password was entered incorrectly a specific number of
times. The duration of the blocking is also configurable.
3a. Maximum Number of Failed Logins
Enter the maximum number of failed login attempts after which
a user should be blocked. Leave this field empty to disable the
user-blocking feature.
3b. Block Time
The number of minutes the user is blocked after he or she has exceeded
the maximum number of failed login attempts. Leave this field empty to
block this user until he or she is manually unblocked.
Unblocking Users
There are two possibilities to unblock a blocked user:
• A parent user may go to the user-management settings (see the "User
Management" section) and press the "Unblock" button for the user.
• An administrator may use the serial console for the initial configuration
and log in as the user "unblock". The RIPM will ask for the administrator
password and present a list of blocked users who may be unblocked.
