Whatsapp not working on ISO

Are you using a proxy ? (Webfilter?)

yes i do, i have a firewall rule when i assign certain ports for services and WhatsApp sites and IPs as destination  it won't work but when i change it to "Any" for both services and Distention it works. 

Then go to Network Protection, Live view and watch, which ports are blocked for that IOS devices, when not using „any“

source port is keeps changing, for distention its 5222 or 5223.

Hello awab elhassan ,

Thank you for reaching out to the community, have you tried allowing the application from the application control ?  For the ref please see the screenshots below:

HI, I am already using this but still its not working.

This are the following ports used by what's app:

TCP Ports; 80, 443, 4244, 5222, 5223, 5228, 5242, 50318, 59234

UDP Ports: 3478, 45395, 50318, 59234

Ensure to create a plain FW rule on the top, and select the action as allow!
And may we know what is the version of the Sophos UTM 9 currently in use ? If you are using any older firmware, request you to upgrade to the latest 9.715-4 released.

firmware is updated  9.715-4, where should i use these ports? firewall? in services? or Distention? 

In services awab elhassan !

what about distention?? i don't want to make it any
