WhatsApp calls/audio uncaught by whatsapp & whatsapp-base Palo rules

L0 Member

Hi,

It seems that WhatsApp calls use SSL and QUIC towards their servers and this is no more caught by whatsapp and whatsapp-base Palo Alto rules.

 

Example of use case: I called from an android smartphone on a limited access (whatsapp allowed) to another android on an open network (all allowed). Find here attached my PA firewall traces related to the call, SSL and QUIC systematically blocked and unrelated to whatsapp.

 

My version of PA is 10.2.4-h3.

I've this issue since at least two weeks.

 

Has somebody met the same issue ?
