Is port 2492 dangerous?

We have no specific security note for port 2492. Its risk depends on the program actually listening on it. General advice for other services services:

  • 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.

netstat -ano | findstr :2492

From another machine

nmap -p 2492 -sV <host>
sudo nmap -sU -p 2492 <host>
nc -zv <host> 2492
