Is port 3218 dangerous?

We have no specific security note for port 3218. 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.

Is port 3218 TCP or UDP?

Port 3218 is registered for TCP and UDP.
