Explanation:
Destination unreachable is generated by the host or its inbound gateway[3] to inform
the client that the destination is unreachable for some reason. A Destination Unreachable message may be generated as a result of a TCP, UDP or another ICMP transmission.
Unreachable TCP ports notably respond with TCP RST rather than a Destination Unreachable type 3 as might be expected.
