Which program uses port 3068, and is it reachable?
Linux
sudo ss -ltnup 'sport = :3068' # process listening on 3068
sudo lsof -nP -i :3068macOS
sudo lsof -nP -i :3068
Windows (PowerShell)

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. Require authentication on cameras and media servers.
How do I check if port 3068 is open?
On Linux run "ss -ltnup 'sport = :3068'", on macOS "lsof -nP -i :3068", and on Windows "netstat -ano | findstr :3068" to see the local process. From another machine, "nmap -p 3068 <host>" shows whether it is reachable.
