Seamless Site-to-Site Connectivity with Peplink FusionHub Solo
Secure CLOUD File Sharing with Data Sovereignty on 1STACK Cloud
Project Background
In modern industrial and remote deployments, cellular connectivity has become the standard for primary and backup internet. However, a significant technical hurdle often exists: many cellular providers assign private IP addresses via Carrier-Grade NAT (CGNAT). This places devices behind a restrictive firewall, making traditional VPN setups nearly impossible.
The Challenge: The “Double-Blind” Scenario
When two remote sites need to communicate, they face a “double-blind” situation. Because both sites are behind CGNAT, neither has a reachable public IP address.
- Connectivity Barrier: Traditional VPNs require at least one side to have a public IP to initiate a handshake.
- Infrastructure Limitation: Without a central anchor, these sites remain isolated, preventing secure data exchange or centralized monitoring.
- Complexity: Standard workarounds like complex port forwarding are often unsupported by cellular carriers.
The Turning Point
The need for reliable, industrial-grade communication—such as for CCTV backhaul, server access, or remote telemetry—requires a solution that bypasses NAT limitations without compromising on security or speed. The realization was clear: the network needed a neutral, publicly accessible “meet-me” point.
Starview’s Solution: 1STACK + Peplink MAX BR1 Mini+ FusionHub Solo
By hosting Peplink FusionHub Solo (the virtualized SpeedFusion engine) on 1STACK Cloud, Starview provides a central hub with a stable, static public IP.
Instead of the remote routers trying to find each other, both BR1 Mini units initiate an outbound connection to the FusionHub. Because the FusionHub is hosted on the high-performance 1STACK infrastructure, it successfully traverses the NAT on both sides, creating a secure, high-performance SpeedFusion tunnel.
Feature | Benefit for Your Business |
Public Cloud Hosting | Deploy on 1STACK with a stable, sovereign public IP. |
NAT Traversal | Seamlessly connect sites with private SIM IPs without complex configurations. |
SpeedFusion Bonding | Combine multiple cellular or wired links for increased bandwidth and reliability. |
Hot Failover | Instant traffic migration if one link fails, ensuring session persistence. |
Centralized Management | Full visibility and configuration via Peplink InControl 2. |
MAX BR1 Mini
The MAX BR1 Mini is an industrial-grade powerhouse designed for the most demanding environments. Its compact form factor belies its capability, offering rugged reliability, versatile connectivity (LTE/5G), and redundant power options.
The Results: Versatile Deployment Scenarios
The implementation of FusionHub Solo on 1STACK enables three primary operational modes:
- Isolated Site-to-Site Communication: All traffic remains strictly within a private VPN tunnel, ideal for high-security internal data.
Scenario 1: Isolated Site-to-Site Communication
- Local Internet Breakout: Sites maintain VPN connectivity for internal tasks while routing general web traffic locally to reduce latency and optimize bandwidth.
Scenario 2: Site – to Site VPN with Local Internet Breakout
- Inbound Port Forwarding: FusionHub Solo acts as a gateway, allowing secure inbound access from the public internet to internal resources like CCTVs or servers, even when they are behind CGNAT.
Scenario3: Site – to Site VPN with Internet Access and Inbound Port Forwarding
Conclusion
By combining the rugged reliability of the Peplink MAX BR1 Mini with 1STACK, businesses can overcome the inherent limitations of cellular networking. This solution transforms restricted mobile links into a robust, site-to-site enterprise network that is secure, scalable, and easy to manage.
