+
+## Create a Firewall Rule in GCP
+
+To expose TCP port 15672, create a firewall rule.
+
+Navigate to the [Google Cloud Console](https://console.cloud.google.com/), go to **VPC Network > Firewall**, and select **Create firewall rule**.
+
+![Create a firewall rule](images/firewall-rule.png "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 "0.0.0.0/0".
+
+![Create a firewall rule](images/network-rule.png "Creating the TCP/15672 firewall rule")
+
+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](images/network-port.png "Specifying the TCP port to expose")
+
+The network firewall rule is now created and you can continue with the VM creation.
