I've set up one of our PAs (a 5260 running 10.1.6-h3) to use as a certificate authority and OCSP responder for use with GlobalProtect remote access. I'm able to issue and verify certificates with no problem, but revoking a client certificate has no effect on whether the able to connect. I'm able to browse to http://<PA IP>/CA/ocsp, but the browser downloads a 0kb file and the device doesn't appear to be updating this revocation information. Do I need to do something else to have the firewall validate this cert?
Does the firewall generate the OCSP request from its own management interface, or the interface it's doing the GlobalProtect auth on? I have the service listener set up on the Management interface but that wouldn't be accessible from the outside if that's the case.
