Procedure:

1) Using the notification function requires the e-mail settings to be configured in the Firewall menu.

2) In this example, e-mails are sent using an external mail server. Enter the access credentials for the mail server into the Relay section.

3) You can check your settings by clicking Send test mail.

4) Switch to the menu Monitoring & Statistics → Notification Settings.

5) Configure the following in the General settings area:

• Notification language: Language used in the notification e-mails. If the dialog is opened for the first time, the language is set to that used by the web client.
  
  
• Subject template: Specify the subject of the notification e-mail here.
  
  
• Recipients: List of recipient addresses where the notifications are sent.
• Aggregated notifications: Events are collected and summarized in an e-mail that is sent at a specified interval.
  
  
  • Aggregation interval: Time (in minutes) over which the events are collected.
    
    
  • number of notifications per mail: Determines how many events are summarized per e-mail and ultimately determines how many e-mails are sent when the aggregation interval expires. If necessary, please observe any spam guidelines of the recipient.

• Instant notifications: The event is immediately reported as an e-mail to the recipient(s).
  
  

Max. number of mails per hour: Depending on the settings in the Notification Types section and the events that occur, large numbers of e-mails could be sent in a short time. This could lead to them being blocked if provider policies at the receiving end are infringed.

To avoid this, you can use this item to restrict the number of instant notifications sent per hour. Instant notifications are additionally sent in the next aggregated e-mail.

6) Configure the following under Notification types:

• Filter: The available notification fields can be filtered by their name and set value.
  
  
• Set for all selected notifications: All notification fields displayed by the filter are set to the value selected here.
  
  For example, all IPSec-related notifications can be set to the value Immediate:
  • Filter = ipsec
  • ... Set notifications = Immediate
