Whatsapp traffic not recognize by palo alto firewall

VirupakshaRajapur — Wed, 16 Aug 2023 13:55:31 GMT

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

Are both devices the same hardware and PAN-OS ?

Did you verify if no APP-IDs have been disabled on one firewall?

Can you verify if (via 'show session info') both devices have the same session setup settings?
