Additional Information
PLEASE NOTE! If required on Transparent mode, please also enable outgoing traffic on port 5222 as Facebook recommends - https://developers.facebook.com/docs/whatsapp/guides/network-requirements/
If you want to link the CPL code to existing combined object (ex.Whatsapp-users) for the users IP that are allowed to access Whatsapp, you'll need to add additional line to CPL:
<Proxy>client.address=Whatsapp-users service.name="Whatsapp" authenticate(no) ALLOW; Disables authentication via Proxy<proxy>client.address=Whatsapp-users condition=WhatsappURLS authenticate(no) ALLOW
[...]
If the above settings does not work:
- please create a static route to the Whatsapp IP ranges on intermediary devices so the traffic won't go via Proxy
- If running EXPLICIT mode the IP ranges or urls can be bypassed in PAC file
