I have a web policy that blocks particular urls of which youtube is a part. The concern that I cannot properly block the youtube.com site on my network when I use the DPI filtering mode.
The site is inaccessible but the notification returned is not the one used by sophos.
However, with the same rules when I use web proxy mode instead of DPI, it works fine.
Is there a way to solve this.?
DPI has a default of "just reject" not notify. Notify in DPI means "block page". Check the TLS Decryption Profile, you are using and build a own profile with action Block and Notify.…
DPI supports some features that are not supported by Web Proxy, and vice versa.
Here's an overview that was written in February of 2021: www.fastvue.co/.../
What do you mean by the block page is not shown? Can you share a screenshot of this?
here is the error I get when I try to access youtube.com
DPI has a default of "just reject" not notify. Notify in DPI means "block page". Check the TLS Decryption Profile, you are using and build a own profile with action Block and Notify.
I customized the decryption profile by putting "reject and notify" on the action block but I still have the same notification. Would I have missed something.
however when I try to access another site like facebook. I have been notified that I had been blocked by sophos
So it started to work now?
No, not yet, it's still the same. I still have the same notification. It has always worked with other sites but not with youtube.
In the log viewer, I have decryption errors for the site in question
