- Close the port if nothing on the host needs it.
- 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.

Which program uses port 2225, and is it reachable?
Linux
sudo ss -ltnup 'sport = :2225' # process listening on 2225
sudo lsof -nP -i :2225macOS
sudo lsof -nP -i :2225
Windows (PowerShell)

From another machine
nmap -p 2225 -sV <host> nc -zv <host> 2225

Port 2225 is registered for TCP and SCTP.
Is it safe to open port 2225?
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 2225 is open?
On Linux run "ss -ltnup 'sport = :2225'", on macOS "lsof -nP -i :2225", and on Windows "netstat -ano | findstr :2225" to see the local process. From another machine, "nmap -p 2225 <host>" shows whether it is reachable.
