What's App video and audio calling blocked (whatsapp)
Posted: Mon Jan 30, 2023 2:02 pm
Hello,
I have a very weird issue on an OPNsense firewall. What's App works for text but when initiating a call, either audio or video, the recipient phone rings, but when picking up the call, it fails to establish the p2p connection and times out. It happens when calling from inside to outside and the other way around.
If the devices are connected on the network, behind the firewall it works. If one is outside the network it fails most of the time BUT not every time ...
Nothing really fancy in the configuration, Web proxy, OpenVPN, IPsec, and some port redirections for a mail server, an HTTP/S server and a STUN (coturn). The bandwidth is 300mbps symmetrical, optical fiber.
I tried pluging in a simple hardware router/DSL modem, and it works as intended this way.
I am stuck.
