Use Cases overview

flexiWAN Open Source SD-WAN solution is designed to meet a variety of network management needs, offering flexibility and robust performance. This document outlines several use cases that illustrate how flexiWAN can be effectively deployed to enhance network efficiency, ensure reliable connectivity, and secure data across different environments. Whether managing connectivity challenges in complex networks, enabling advanced features like high availability, or optimizing SaaS access, flexiWAN equips organizations with the tools to tailor their network infrastructure to specific operational goals.

Connectivity

  1. Running flexiWAN Behind NAT/Existing Router

    Organizations can deploy flexiWAN in environments with pre-existing network setups, utilizing NAT traversal to maintain smooth connectivity without requiring changes to the main infrastructure.

  2. Failover Using LTE and Wired Interfaces

    By configuring flexiWAN to automatically switch between wired and LTE connections, businesses can ensure uninterrupted connectivity, even when the primary network link fails.

  3. Cloud Connectivity

    Establishing direct and secure connections from branch offices to cloud service providers reduces latency and enhances performance, bypassing traditional routing through central data centers.

  4. Tunnel Failover in Multi-Branch Enterprises

    Multi-branch organizations can set up multiple active tunnels through different ISPs, allowing for real-time traffic distribution and automatic failover, ensuring continuous and optimized operations.

  5. Optimized SaaS Access

    flexiWAN’s application-based routing enables businesses to route SaaS application traffic through the best available paths, ensuring low latency and high performance for critical applications.

  6. Seamless Remote Access with Geo-Aware Remote Worker VPN

    Remote employees can securely access company resources with minimal latency, as flexiWAN’s Geo-Aware VPN automatically connects users to the nearest flexiEdge, optimizing bandwidth and performance.

Deployment

  1. High Availability - Hardware Redundancy

    Critical branch locations can achieve continuous connectivity by deploying dual flexiWAN devices configured with VRRP, ensuring one device can seamlessly take over if the other fails.

  2. Network Segmentation

    By integrating VLANs with flexiWAN, organizations can implement detailed network segmentation, isolating various types of traffic to enhance both security and performance.

  3. Application Prioritization

    Businesses can prioritize essential traffic, such as VoIP, over their highest-quality links using flexiWAN’s Path Selection and Quality Based Routing, ensuring clear communication even during peak usage.

Advanced

  1. Secure Data Routing

    flexiWAN’s smart tunnel management ensures that sensitive data is always routed through the most secure, encrypted tunnels, protecting critical transactions and communications.

  2. High Availability Across Multi-Cloud Environments

    Organizations can configure flexiWAN across multiple cloud platforms, ensuring redundancy and continuous service even in the event of a cloud provider failure.

  3. Centralized Management for Large-Scale Deployments

    flexiWAN’s centralized management capabilities simplify the oversight and optimization of large SD-WAN deployments, making it easier to manage complex network environments.

  4. Integration with Third-Party Security Solutions

    Strengthening network security by integrating flexiWAN with third-party solutions, such as firewalls and intrusion detection systems, allows organizations to build a comprehensive, layered defense strategy.
