Certificates for DPI
We are looking to enable DPI on all of our firewalls. I have about 15 firewalls in total. I also have a local Enterporise CA which i am going to use for the certs. When it comes to creating the certificates for the dpi for outbound traffic do I have to create a certificate for each firewall or can I create one certificate and import that into all of my firewalls. Id much rather manage one cert than 15 individual ones if possible.
