URL Response Page for SSL without decryption

rjdahav163 — Tue, 14 Aug 2018 14:03:31 GMT

Hello everyone,

we have PA7050 managed by panorama. We dont have SSL decryption but we want to serve users a block url response page for https traffic. For that I followed following link:

https://live.paloaltonetworks.com/t5/Configuration-Articles/How-to-Serve-a-URL-Response-Page-Over-an-HTTPS-Session-Without/ta-p/55998

But this doesn't seem to work with 7.1.18.

I have 2 doubts:

1. For the fwd-trust and untrust certificates - I just created them and ticked the approrpiate check box by clicking on the certificates. Do I need to do any additional step?

2. Since I cannot give the command "# set deviceconfig setting ssl-decrypt url-proxy yes" on panorama, I logged on to the FW CLI and then gave this command and then committed from the firewall CLI itself. Is this wrong?

Best Regards,

hi @rjdahav163

1. After you create the certificates and checked the boxes, you will need to commit

2. This setting does need to be set on the firewall locally, so that should be good.

Hello,

I have the same issue with Panorama and 2 PA7050 with 8.1.9-h4.

In logs, I see the Session End Reason as a decrypt-error.

This error is caused, according to documentation:

"Decrypt Error. The session terminated because the firewall was configured to block SSL forward proxy decryption or SSL inbound inspection when firewall resources or the hardware security module (HSM) were unavailable. This session end reason is also displayed when the firewall is configured to block SSL traffic that has SSH errors or that produced any fatal error alert other than those listed for the decrypt-cert-validation and decrypt-unsupport-param end reasons."

I can't believe that a PA7050 can have resource problems to cause this problem.
