I want to renew the expiration date of the certificates for my globalprotect devices. The firewall is the CA that issued the certificates.
My question is whether I have to export and import the certificates after renewing them by following the steps on this article:
I don´t know if the certificates renewal requires any installation or the changes will be reflected in the devices without installation.
Many thanks in advance,
There are two possibilities for which you may be using the Device (locally) generated certificate :
1. Server Certificate for Portal and Gateway : In this case the signing CA cert is still the same and has not changed.
Hence the end users would still be able to validate the new server certificates as they have the signing CA cert.
2. Client Certificate for Authentication of End users : If this certificate has expired and renewed then it needs to be imported
on the local devices (clients). If not, they would not authenticate the local machine due to expiry.
Many thanks for your answer.
Just two last questions:
1) In the end users can the new certificate overwrite the old one or is it necessary to remove the old certificate before installing the new one??
2) If I want to renew the expiration date of the CA root certificate which signed the server and client certificates I guess that I need to export this one to the end users as well, right??
Thanks and Regards,
Please find the answers to your questions below :
1) I would recommend you to remove the older certificate from the personal store and add the new one. Certificate management is usually done with GPO, you may use the same to deploy/withdraw the certs.
2) Yes, in case the signing CA certificate is renewed, it needs to be imported on the client machines and added in the Trusted Root CA store.
Please mark as a solution if it resolves your problem.
Thanks for your response.
Also make sure that if the Client certificate is generated on firewall you export it in format PKCS12.

I know it's been a while since you've made this post, so I hope this message finds you well.
Since the certificates were generated on the firewall, we have the ability to renew them directly from the PAN-OS without having to re-deploy them.
I've included the document explaining this in further detail below for your reference.
Stay safe and have a great day!
