GP Certificates and SSL Decryption

L3 Networker

Hi All,

 

I have configured GP in PreLogon mode so there is a machine certificate deployed.

 

My certificates are locally generated on the Palo Alto. The Local CA certificate is due to expire and the SubCA expires shortly after. What will happen to user connections if I renew both certificates for another year using the renew button. Am I going to have to export the new certificate to all devices that connect using GP PreLogon? Just being cautious to not prevent outage.

 

Also, with the same Local CA - is it okay to create further SubCA for SSL Forward Encrypt and Forward Decrypt? Apologies for a simple question, I cannot have an outage on this user so just validating my thoughts (which is yes).

 

Regards

 

Adrian

I played about with this and came up with a solution. The certificate extension using the renew button had no impact on my user connections but had to be pushed out to users.

 

I created the Root cert for SSL decryption and the intermediates for Decrption Forward Trust and Untrust. All worked well. I also created a seperate certificate for the new Machine Cert and this tested okay. Simplified the solution and labelled the certs so there is better understanding for other engineers.

for your pre-logon...   are you talking about exporting a new machine cert as i was never aware that the root or subca needed to be exported for pre-logon to work...
