How To - Block WhatsApp
Posted by , Last modified by Jim Giseburt on 21 July 2017 03:58 PM

WhatsApp Messenger is a widly-available, cross-platform proprietary instant messaging subscription service. It allows users to communicate via text messages and to share a wide variety of content and data, such as videos and location, without incurring text messaging fees. WhatsApp was acquired by Facebook in February 2014.

Blocking WhatsApp

WhatsApp makes use of the following ports; 4244,5222,5223,5228,5242

When it cannot communicate on those ports it fails over to using ports 80 and 443.

Firewall

Block either all incoming and outgoing, or just outgoing communications on ports 5244,5222,5223,5228,5242.

Blacklist

You will want to add the follow addresses to either the invididual groups blacklist, or the global blacklist.

  • whatsapp.com
  • whatsapp.net

 

Notes:

Some of these ports are used for other popular services and will disable them as well

Port 5222 & 5223 are used for XMPP communication

Port 5228 is used for HP Virtual Room and Google Play
