A payment gateway is a service that helps businesses start and receive payments. It works like a link between a business’s website or point-of-sale (POS) system and allows them to accept payments in different ways, such as online, through apps, or in person. To redirect subscribers to a payment page using Zal Ultra on MikroTik or other NAS (Network Access Server), the process generally involves these steps:

1. Use a Captive Portal with Zal Ultra

Zal Ultra likely has built-in support for a captive portal, which can redirect users who haven’t paid to a specific payment page.

• Install Hotspot or PPPoE Server: On MikroTik, the Hotspot or PPPoE features are used to manage subscriber access, allowing Zal Ultra to handle authentication.
• Custom Login Page: Zal Ultra may allow you to configure a custom login page where subscribers are automatically redirected to the payment page if their subscription has expired.
• You can customize the Hotspot login HTML files on MikroTik to include a redirect to your payment gateway via Zal Ultra.

2. Integrate Zal Ultra with RADIUS Server

If Zal Ultra supports RADIUS, you can use RADIUS to manage user authentication and payment status.

• Billing System Integration: Zal Ultra integrates with your billing system to check if the subscriber has paid. If not, the RADIUS server can assign the user a limited access profile that redirects them to the payment page.
• Change of Authorization (CoA): When a user’s payment status changes, Zal Ultra can trigger a CoA request to update the user’s session and force redirection to the payment page if needed.

3. Firewall Redirection via Zal Ultra

Zal Ultra may also support creating firewall rules to redirect non-paying users.

• Mark Non-paying Subscribers: Zal Ultra can flag non-paying users, and through firewall rules, you can redirect their traffic to a payment page.
• NAT Rules in MikroTik: Use destination NAT rules in MikroTik to forward all traffic from unpaid users to the payment URL.cssCopy code/ip firewall nat add chain=dstnat src-address=unpaid-user-ip action=dst-nat to-address=payment-page-ip

4. Automation of Payment and Redirection

Zal Ultra likely includes automated workflows to redirect users based on payment status. For example:

• After login, Zal Ultra checks if the user has paid. If not, the user is automatically redirected to the payment page. After that, it’ll show you a form to fill up and give you several option for payment. You can choose your suitable payment method.
• Once the payment is made, Zal Ultra sends the necessary updates to MikroTik or the NAS to restore full internet access.

5. Customization and Third-Party Tools

If Zal Ultra doesn’t handle all aspects directly, you can integrate it with third-party tools like FreeRADIUS, Splynx, or other ISP management tools that automate redirection based on payment status.

Summary

• Captive Portal & Login Page: Use Zal Ultra to manage captive portals and redirect non-paying users to the payment page.
• RADIUS & CoA: Integrate Zal Ultra with a RADIUS server to handle authentication and enforce redirection when payments are overdue.
• Firewall Rules: Use Zal Ultra to manage firewall redirection for non-paying users, ensuring they are sent to the correct payment page.

This method ensures that Zal Ultra effectively manages subscribers and automates redirection to payment pages, keeping your workflow smooth and efficient.

Conclusion

Integrating Zal Ultra ISP CRM with MikroTik or other NAS devices for payment management is an efficient and automated way to handle subscriber billing and internet access. By utilizing captive portals, custom login pages, RADIUS server integration, and firewall redirection, ISPs can seamlessly redirect non-paying subscribers to a payment gateway, ensuring timely payments while maintaining full control over network access. Automation within Zal Ultra further simplifies the process by instantly restoring access after payment, streamlining operations and improving customer experience. This integration allows ISPs to focus on delivering high-quality service while ensuring a secure, user-friendly payment process.
