File blocking is not happening .!

Hi team,

I have a file blocking profile for upload direction for all type of applications and file types.

I am using Decryption as well, Only in Google Drive File blocking is happening in so weird manner.

Pdf's and jpegs are getting blocking if only they are in less than 1MB, if they are more than 1MB files are getting uploaded.

I see the traffic is http/2 stream also I tested with striping the ALPN, when downgrading to http1.1 , file block happening for all regardless of any file size.

But customer not willing to downgrade and wants to know why it is happening for http/2 .!

Tested in PAN OS 9.0.10 & 9.1.6 with latest content version and also with an old multiple versions, behavior is same.

Any advise .?

Regards,

Sahithyan

hi @sahithyan.subbu sorry for the late reply

The only thing i can imagine at this time is that the decoder may have trouble keeping track of all the 'large' files in the same flow. you may want to open a support request with PAN to have this looked at as it may be a shortcoming/limitation/bug in the http/2 decoder
