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.…
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
