2020 Network - Filtered Ports

Searching through the 2020 documentation, I am not seeing anything about the radio filtering/restricting ports on the network. I believe the RIO would still only have certain user ports, but is it a free for all regarding ports for other components on the network? And would this also be true when attempting to connect to services from the wifi side. Example: ssh to a pi on the robot from the driver station (port 22), etc?

Part of the competition manual each season includes which ports are open for teams when connected to FMS.
