Hi,

In one of the Palo alto firewall Whatsapp traffic is detected as “unknown-tcp” for destination port 5222.

Only mobile phone users Whatsapp traffic is detected as “unknown-tcp” & Whatsapp web traffic is allowed for destination port 443 & 80.

On the other PA firewall Whatsapp traffic is detected as “whatsapp-base” for destination port 5222.

Downloaded & installed the latest applications and threats content updates but no luck. 

Model: PA-3020

PAN-OS: 9.1.16

Kindly suggest the cause of the problem. 

 

Regards,

Dhiraj
