Hi @etofran810,

Are you still on local vmware? Which one of your Kubernetes cluster instances has the public IP 35.184.217.9 ?

Regards,

Hello,

I see that you were able to ping. Which is good, but does not disclose if you have opened all ports. Have you reviewed the setup video or lab intro which mentions that all traffic must be allowed. I suspect while ICMP may work, and SSH works, the random high port is not allowed.

Take a look at this video to help: https://training.linuxfoundation.org/cm/LFS258/LFS258-GCE-Setup.mp4
The username and password are in the book.

Regards,

etofran810

yes, I have opened all port

Hi @etofran810,

My Spanish is a bit rusty, and I cannot see a rule that allows all traffic from all sources, to all ports and all protocols.
Would you mind highlighting that particular rule?

Regards,
