-Access Couchbase's web UI by launching your preferred web browser and navigating to either the reverse DNS address of the *cluster provisioner*. This is the instance labeled `couchbase-occ-1-$region-$uuid`. If you need assistance in finding your instance's IP addresses and rDNS information, refer to the [Managing IP Addresses](/docs/products/compute/compute-instances/guides/manage-ip-addresses/) guide for detailed instructions.

Refer to the [Managing IP Addresses](/docs/products/compute/compute-instances/guides/manage-ip-addresses/) guide for instructions on how to find your instance's IP addresses and rDNS information.

 While there are no buckets yet configured on this new cluster, you can see all five nodes marked ready on the bottom status bar, and verify the status of the cluster members from the Servers tab.

+### Managing Firewall and Security
+
+The Couchbase Cluster deploys with preconfigured UFW firewall rules. These rules limit allowed traffic on node-to-node and cluster-to-cluster Couchbase ports to IP addresses within the cluster.
+
+Only the *cluster provisioner* has firewall access configured for web and client ports.
+
+The Couchbase Enterprise Server Cluster Marketplace App manages these UFW configurations with `application profile` files in the `/etc/ufw/appplications.d` directory. See [Configure a Firewall with UFW](/docs/guides/configure-firewall-with-ufw/) for more details on using UFW.

 ## Next Steps
 
 Now that your Couchbase Enterprise Server One-Click Cluster has been deployed, contact [Couchbase Support](https://www.couchbase.com/pricing/) to activate your license on this newly deployed cluster before using the cluster for testing, quality assurance, or in production. An active Enterprise License is required for any use other than solely for internal development use or evaluation of the software.
