flexiWAN release 6.4.1: New AI Agent and Performance Enhancements

Brand new flexiWAN version brings many features and improvements we’re excited about, starting from expanded LAN NAT functionality, AI improvements, greater recovery functionality and more! Let's dive into the key improvements.

LAN NAT 1-to-Many (NAPT)

flexiWAN version 6.4.1 expands on our existing NAT capabilities by adding LAN NAT 1-to-Many (NAPT). With this feature, LAN NAPT extends the 1:1 NAT functionality by allowing an entire LAN subnet to be NAT-ed to one or more configured NAT IP addresses. It functions as a Many-to-1 NAT, enabling multiple devices on a LAN to share a single or several NAT IP addresses.

Meet the New flexiWAN AI Agent

Introducing a smarter way to manage your network—the flexiWAN AI Agent. This new tool acts like a virtual assistant, helping you navigate configuration and troubleshooting tasks. If you’ve ever had a question about configuring routing or wondered how to fix an issue, the AI Agent is ready to help.

Designed to make SD-WAN management easier, the AI Agent offers solutions to common issues and guides you through complex steps. It learns from user interactions and network patterns to provide tailored suggestions, making network management more accessible whether you’re new to flexiWAN or a seasoned pro. To understand how it works in more details, check out flexiWAN’s AI Agent documentation pages here.



Link Monitoring Gets a Boost

We understand that keeping an eye on network health is crucial. That’s why we’ve made significant upgrades to link monitoring in flexiWAN version 6.4.1. Now, you can customize monitoring parameters for WAN links and individual connections, giving you a clearer picture of network performance.

Set specific monitor IP's or HTTP requests, thresholds, track latency, monitor packet loss, or create recovery actions based on the parameters you define. With this level of control, you can spot potential issues before they affect your users. It's all about proactive network management to keep things running smoothly.

Expanded Hardware Support: Dual SIM – Single Modem

Network reliability takes another step forward with support for dual SIMs on a single LTE modem. While flexiWAN previously supported dual or more SIM cards, using dedicated LTE modems, now we are introducing support for dual SIM Single Standby mode. This allows having two SIM cards working with a single supported LTE modem.

A big thank you goes out to our hardware partner, Portwell, whose collaboration provided the ANS-9122 device with Telit LN920A6-WW LTE, used to bring this feature to life. The dual SIM support not only enhances reliability but also adds flexibility to LTE-based deployments, ensuring that your network stays online even when one provider experiences disruptions. 



Connection Recovery: Built-In Resilience

The new Connection Recovery feature in flexiWAN 6.4.1 ensures your devices stay connected to flexiManage, even when network issues arise. It automatically detects and responds to connectivity failures by attempting to restore the connection using a series of recovery steps, such as reverting to default configurations or using saved recovery settings.

The process activates when WAN failures occur, reconnect attempts to management are unsuccessful, or misconfigurations are detected, minimizing downtime and reducing the need for manual intervention. If automated recovery fails, the system pauses further attempts and signals the need for manual troubleshooting, ensuring network resilience at all times. Learn more about Connection Recovery here.

Edge Loopback: Simplifying Access and Routing

With the addition of the Edge Loopback feature, flexiWAN 6.4.1 makes accessing edge devices and managing routing more flexible. Edge Loopback allows users to configure a local IP for the edge or gateway that is routable and reachable from other edges. This feature provides an alternative IP address for accessing edge devices, especially useful when multiple edges share the same LAN subnet and IP ranges.

For more details, visit the Edge Loopback documentation.



Under-the-Hood Improvements

While the big features often grab the spotlight, the smaller improvements matter too. In version 6.4.1, we’ve updated the Linux kernel to version 5.15, which brings better hardware compatibility, security patches, and general stability improvements. We’ve also made optimizations to tunnel scaling, job processing, and streamlined the Device Host OS Upgrade feature. Lastly, flexiWAN's QoS is now complete with full bandwidth control over upstream and downstream.
