I send a UDP packet to Oracle Cloud Compute instance. It doesn't get there.


On Oracle Cloud Compute instance, I run "netcat -u -l -p 20000".

On my home computer I run "echo hello|netcat -u 20000".  Packet never gets to my Oracle Cloud Compute instance. is my Oracle Cloud Compute instance public IP address.  "ping" works from home.  "ssh [email protected]" works.

If I run "netcat -u -l -p 20000" on my home computer and run "echo hello|netcat -u myhomecomputer 20000", then packet gets to my home computer.

In my Security List I have a single ingress rule that says "All traffic for all ports" under "allows".


Howdy, Stranger!
