Hello,
I have a self-signed (self-generated) certificate without a Root CA on a firewall, which is used for SSL Forward Proxy to decrypt traffic.
The certificate is valid for 10 day and has been imported on client machines as a trusted root CA.
The question is that : If I renew this certificate on the firewall, will I need to re-import it on the clients, or can they continue to use the old/expired trusted CA?
In lab tests, the key pair on the firewall did not change after renewal, and clients still trusted the old certificate.
Has anyone encountered a similar scenario or can confirm this behavior?
Thank you.

Hi @f.kuecuek ,
Greetings!
Yes, you will need to re-import new certificate on the clients with updated expiry date.
