Opening up a UDP port for incoming traffic

I’m following this tutorial and it mentions that I need to open UDP port 3478 for incoming traffic on the STUN server.

If I deploy an elixir/ phoenix app using Render, will I be able to open the port for incoming traffic? If so, how would I make sure the port is open on Render?


Hi @heartanswer ,

Render only supports connections with the public Internet over HTTPS. As far as I know, UDP traffic support is not currently on our roadmap.
