GCP - Cannot ping instances


I am trying to setup instances on GCP for the training and am having problems with inter-instance communication. I the instances can ping the Internet but cannot communicate with each other. The firewall appears to allow ICMP, HTTP, and HTTPS traffic, but I can't figure out what else is wrong. Can anyone recommend troubleshooting steps?

    Hi @kbreit,

    Your current firewall rule(s) may be too restrictive. Read carefully the overview section of lab exercise 3.1, it provides tips on a firewall rule you may need to add.

    I deleted my instances and started over. It seems to have solved the problem. Thank you.
