Google Compute Engine: How can I disable the firewall of VM instance?
<p>I have used firewall rules but I still cannot receive traffic on vm instance. I want to allow http server incoming connection. By default google compute engine does not allow incoming traffic outside the network, so you have to create firewall rules. In google cloud platform documentation it suggests to disable operating system firewall. To disable it I need my user password, which I never created. So what to do now? I need password for my user, I am the creator of vm instance. Any help?
These are my firewall settings:</p>
