Centel Group Solves IPv4 Shortage with NFWare CGNAT
Facing Australia’s ongoing IPv4 address exhaustion, Centel Group—a regional ISP formed by the merger of IP Telco and Centra Networks—needed a scalable solution to support internet services for new subscribers. With IPv6 adoption still limited and purchasing additional addresses from brokers leading to potential issues, the company chose to deploy NFWare’s virtual CGNAT after a thorough evaluation of the market.
The virtual solution proved quick to deploy, easy to manage with a familiar CLI, and fully compliant with local regulations. By using only eight IPv4 addresses, Centel was able to serve over 1,000 users without any impact on user experience—even with high-demand applications like streaming and gaming. The transition went smoothly, with zero customer complaints and a reliable, high-performance result that exceeded expectations.

Challenges
Need for Rapid Deployment – With new housing projects underway, Centel needed a solution that could be tested and rolled out quickly.
Effects of Implementation
Efficient Address Utilisation – Centel supported over 1,000 users using just eight public IPv4 addresses, freeing up others for business clients.
Seamless User Experience – Customers experienced no disruptions, even with demanding applications like gaming and streaming.
Smooth Deployment and Scalability – The solution was easy to trial and install, integrated well with existing systems, and offered room to scale as needed.
Compliance with Local Regulations – The solution had to meet Australia’s strict data logging requirements.
Maintaining Service Quality – Any address strategy had to avoid degrading performance, especially for real-time services like VoIP and gaming.
We’ve tested plenty of CGNAT solutions over the years, but NFWare was the only one that truly ticked all the boxes. From smooth integration with our existing infrastructure to outstanding performance and stability under load — it simply works. No fiddling. No firmware drama. Just fast, reliable CGNAT the way it should be.
