No Block Page when accessing Blocked Categories over HTTPS

[Bocsa]

Hi there,

I have recently noticed that when I test access to URLs of blocked categories over HTTPS, I do not get a 'Blocked Page' display from the Palo. It just says the Page Cannot be Displayed and show the connection was reset.

The URL filtering log correctly show as 'Block-URL' for the action. I just do not get a 'Block Page'. 

SSL decrypt is not configured.

How can I get a block page for blocked categories over HTTPS, without SSL Decrypt.

Your assistance is appreciated

Hi,

I had tried this earlier. It doesn't solve the problem. In my case all it did was give me a message saying 'The Connection to the Site is Not Trusted' (ie the standard message you get when accessing an SSL site without a Trusted Certificate.

I still do not get a 'Block Page'

@Bocsa,

The security warning could have been a few things:

1) The Forward Trust certificate wan't trusted by the client, this cert actually needs to be imported and trusted by the clients.

2) The site you were attempting to visit wasn't a trusted certificate, so it served the Forward Untrust cert.

You also need to enable the ability to inject the response pages within an HTTPS session which could also be the issue. Are you sure that you ran the 'set deviceconfig settting ssl-decrypt url-proxy yes'  command, without this setting then the device won't inject the response pages.

''You also need to enable the ability to inject the response pages within an HTTPS session which could also be the issue''.....I'm not sure of what you mean by enable to ability to inject the response pages here.

Yes, I have put in the command 'set deviceconfig settting ssl-decrypt url-proxy yes'
