How to Configure a Firewall Whitelist for Zenduone Application

Overview:
The Zenduone application requires specific domain access to function seamlessly. To ensure uninterrupted service and prevent network restrictions, it's essential to whitelist certain domains on your firewall. This article outlines how to configure your firewall to allow traffic to the required Zenduone domains and associated services.

Domains to Whitelist:

To ensure Zenduone operates without issues, the following domains must be whitelisted:

1. zenduit.com

2. zendu.one

3. *.zenduit.com (Wildcard for all subdomains under zenduit.com)

4. *.zend.one (Wildcard for all subdomains under zend.one)

5. ewatch.video

These domains are essential for the proper functioning of key features in the Zenduone application, such as communication, updates, and media streaming.

Steps to Whitelist Zenduone Domains:

Step 1: Access Your Firewall Configuration

Depending on your firewall solution, access your firewall configuration interface. This could be through:

• A dedicated software firewall

• Hardware firewall device (e.g., Cisco, Fortinet)

• Cloud-based firewall (e.g., AWS Security Groups, Azure Network Security Groups)

Step 2: Add the Domains to the Whitelist

For most firewalls, you’ll need to specify the domains you want to whitelist in one of two formats:

1. Domain Names: If your firewall allows adding domain names directly, input the following:

   • zenduit.com

   • zendu.one

   • *.zenduit.com

   • *.zend.one

   • ewatch.video

2. IP Addresses: Some firewalls require adding IP addresses. If you're unable to directly whitelist the domains, you'll need to resolve these domains to their IP addresses and whitelist the corresponding IPs. You can use a DNS lookup tool (e.g., nslookup) to get the IP addresses associated with the domains.

Step 3: Allow Inbound and Outbound Traffic

Ensure that the firewall rules are set to allow both inbound and outbound traffic for these domains. Typically, this would involve configuring the following:

• Inbound traffic: Allow connections from the specified domains to your network.

• Outbound traffic: Allow your systems to initiate communication with the specified domains.

Make sure that your firewall configuration reflects the protocols required by Zenduone. Common protocols include HTTP (port 80), HTTPS (port 443), and possibly additional ports for specific features.

Step 4: Save and Apply the Configuration

After adding the domains, save your firewall settings and apply the changes. It's a good idea to monitor the firewall logs to ensure the traffic is correctly being allowed for the whitelisted domains.

Troubleshooting:

If you experience issues after configuring the whitelist, consider the following steps:

1. Verify Domain Resolution: Ensure that the domains are resolving correctly to their corresponding IP addresses.

2. Check Firewall Logs: Review firewall logs to check for any blocked requests or errors related to the domains.

3. Contact Support: If issues persist, contact GoZen Helpdesk for further assistance, providing details of your firewall configuration.

Best Practices:

• Regular Updates: Periodically check for updates to the Zenduone domain list, especially in case new domains or IP ranges are introduced in future releases.

• Testing: After configuring your firewall, test all features of Zenduone to confirm that there are no connectivity issues.

• Automated DNS Resolution: Some firewalls allow you to configure rules based on DNS resolution. Enabling this feature can ensure that any IP changes associated with the Zenduone domains are automatically handled.

Conclusion:

Whitelisting the necessary domains ensures that the Zenduone application runs smoothly without interruptions caused by firewall restrictions. By following the steps above, you can ensure that your firewall configuration is properly set to allow Zenduone’s communication and services.
