Looking for a way to find out who or what device is blocking traffic on a specific port. Sort of like a trace route tool where you could designate the port to test with (UDP/TCP). I realize that UDP may be hard to do since it is a connectionsless protocol.
On Unix-like systems use tcptraceroute for TCP and the normal traceroute for UDP packets (option -p). On Windows you can use tracetcp [1] for TCP packets, but I don't know a tool for tracing UDP packets (tracert does not support this).
