what are the whatsapp port numbers?

Update question about whatsapp ports:

According to official facebook:

5222
443

According to screwloose:

TCP: 4244,5222,5223,5228,5242
TCP/UDP: 50318,59234
UDP: 3478,45395

According to quora:

TCP Ports; 80, 443, 4244, 5222, 5223, 5228, 5242, 50318, 59234
UDP Ports: 3478, 45395, 50318, 59234

According to user github:

TCP = 80, 443, 4244, 5060, 5061, 5222, 5223, 5228, 5282
UDP = 5060-5061, 5242, 9785, 40000-60000

According to netify:

TCP 5349
UDP 3478

According to "someone on the internet":

TCP 4244:5242

as I see it, there is no unification of criteria.

Question: What are the real TCP/UDP ports used by WhatsApp (sending/receiving messages and voice/video calls)

Solution 1:

Squid is a proxy, not a firewall.

Even if you could proxy non-web traffic through Squid, there is no way to tell WhatsApp to use your proxy.

You need to allow that traffic through your firewall.

I use a transparent proxy .. which blocked my whatsapp calls ... the problem was solved by releasing the UDP / 3478 port in the firewall
