Allow Whatsapp through the firewall

Hi,

Ports mentioned online seem to include TCP/80 , TCP/443, TCP/5222 , TCP/5223 and TCP/5228

I would suggest testing this on a single device and checking logs through ASDM.

Perhaps even taking a capture of the clients traffic at the firewall might help a bit.

Isnt this a mobile device application? I have not used it myself.

Hi jouni,

It is a mobile application that works on android, mac and symbian. the application port and address keeps changing with every user session. however, I will complete the tests and get back to you with the result.

Agree with Jouni,

Due to the nature of this applications the best way to see this would be with a capture,

Let us know as soon as you have it
