- 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.

Windows (PowerShell)
Get-NetTCPConnection -LocalPort 224 -State Listen | Select LocalAddress, OwningProcess Get-NetUDPEndpoint -LocalPort 224 netstat -ano | findstr :224
From another machine
nmap -p 224 -sV <host> sudo nmap -sU -p 224 <host> nc -zv <host> 224

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 224 is open?
On Linux run "ss -ltnup 'sport = :224'", on macOS "lsof -nP -i :224", and on Windows "netstat -ano | findstr :224" to see the local process. From another machine, "nmap -p 224 <host>" shows whether it is reachable.
