CoAP port only?

I have a device at a school and I may need to put my device on one of the school’s visible networks (see my “Can’t connect Argon to hidden SSID…” post). However, it appears the visible network is locked down to only a few ports and I’m guessing CoAP 5683 is not open. Am I correct in understanding that’s the only port I need open and is it for TCP and UDP? I’d like to make just one request to their IT department and not bumble through multiple requests.

Argon should be using UDP on port 5684 (PORT_COAPS).
