- Identify the process that listens on it (commands below) before opening it in a firewall.
- Expose a service only to the networks that use it.

From another machine
nmap -p 2447 -sV <host> sudo nmap -sU -p 2447 <host> nc -zv <host> 2447

Port 2447 is registered for TCP and UDP.
Is it safe to open port 2447?
It depends on the program that listens on it. Open it only for a service you know and only to the networks that need it. Close the port if nothing on the host needs it.
How do I check if port 2447 is open?
On Linux run "ss -ltnup 'sport = :2447'", on macOS "lsof -nP -i :2447", and on Windows "netstat -ano | findstr :2447" to see the local process. From another machine, "nmap -p 2447 <host>" shows whether it is reachable.
