Description
This article describes how to configure local certificate expiry Automation trigger with an email notification action.
The main use case is to be notified by email if any local certificate is expiring, so the certificate can be changed before expiration.
Scope
FortiGate v7.2.1 onward.
Solution
One might want to remind an administrator to re-sign or load a new local certificate to avoid any service interruptions.
To achieve this, follow the steps below:
First, configure the certificate expiration warning using the following commands.
config vpn certificate setting
set cert-expire-warning 14
end
Note:
cert-expire-warning 14 --> Number of days before a certificate expires to send a warning.
Set to 0 to disable sending of the warning (0 - 100, default = 14).
After this Logs are generated when a local certificate is a near expiry.
When a local certificate log is generated, any automation stitches configured with the local-certificate-near-expiry automation trigger will run.
