Create a firewall rule in GCP

To expose TCP port 15672, create a firewall rule.

Navigate to the Google Cloud Console , go to VPC Network > Firewall, and select Create firewall rule.

Create a firewall rule

Next, create the firewall rule that exposes TCP port 15672. Set the Name of the new rule to “allow-tcp-15672”. Select your network that you intend to bind to your VM (default is “autoscaling-net” but your organization might have others).

Set Direction of traffic to “Ingress”. Set Allow on match to “Allow” and Targets to “Specified target tags”. Enter “allow-tcp-15672” in the Target tags text field. Set Source IPv4 ranges to your IP address so that only you can access the application.

Finally, select Specified protocols and ports under the Protocols and ports section. Select the TCP checkbox, enter “15672” in the Ports text field, and select Create.

Specifying the TCP port to expose

What you’ve accomplished and what’s next

You’ve successfully created a firewall rule to allow TCP traffic on port 15672 for the RabbitMQ management interface. This firewall rule will be applied to your virtual machine using network tags. Next, you’ll provision the Google Axion C4A Arm virtual machine.
