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.

2f. Appending a Rule

Enter the IP/mask and set the policy. Finally, press the “Append” button.

2g. Inserting a Rule

Enter the rule number and the IP/mask. Set the policy. Finally, press the “Insert” button

2h. Replacing a Rule

Enter the rule number and the IP/mask. Set the policy. Finally, press the “Replace” button.

2i. Deleting a Rule

Enter the rule number and press the “Delete” button.

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.
