Zyxel Networks is pleased to announce the release of uOS1.32 for the USG FLEX H Series. This update introduces powerful new features, advanced security enhancements, and tools to simplify network management across both local and cloud environments.


Smart Sync – Manage Seamlessly

Experience revolutionary synchronization between the cloud and your on-premise devices with Zyxel’s advanced Smart Sync technology. This innovation allows you to:

  • Seamlessly access and apply configurations across your ecosystem
  • Control granular settings instantly
  • Stay aligned with real-time updates and preference management

Unlock a seamlessly connected future with synchronized network operations like never before.


DoH and DoT Blocking and Monitoring

Ensure safer browsing and greater network transparency with built-in DNS over HTTPS (DoH) and DNS over TLS (DoT) blocking. When the firewall detects encrypted DNS queries to known DoH servers, it:

  • Blocks them to enforce web usage policies
  • Enhances DNS traffic visibility
  • Maintains overall network health

This feature is ideal for administrators enforcing strict content filtering and monitoring.


Borderless Connectivity with Tailscale VPN (Local Only)

Integrate your USG FLEX H device into a modern, zero-trust mesh network with Tailscale VPN. Now supported as a local-only feature, it allows:

  • Deployment as a Tailscale VPN node
  • SSO/MFA with Entra ID
  • Seamless NAT traversal for simplified remote access

Perfect for individuals, SMBs, or MSPs managing distributed environments with security and ease.


Nebula VPN Orchestrator – Simplified and Comprehensive VPN Management

The Nebula VPN Orchestrator revolutionizes VPN deployment and management, supporting:

  • SD-VPN (Nebula VPN)
  • Auto-link VPN (Non-Nebula VPN)

It delivers:

  • Seamless device integration
  • Effortless hybrid deployment
  • Centralized control over all your VPN connections

Create, manage, and scale VPN topologies faster than ever.


Integrated AP Controller (Local Only)

The USG FLEX H Series now includes a built-in Access Point Controller, enabling direct wireless network management from your gateway. This includes:

  • Centralized configuration and policy deployment
  • Performance monitoring and updates
  • Intelligent client balancing (USG FLEX 50H/HP models also supported)

Reduce hardware costs and streamline wireless operations directly from your existing device.


Additional Enhancements

uOS1.32 also brings a variety of functional improvements to enhance network performance and user experience:

  • Captive Portal: Secure sign-on for network access with authentication support
  • Link Aggregation (LAG): Combine Ethernet links for increased bandwidth and redundancy
  • Route Traces: Use 5-tuple filtering to identify traffic drops and troubleshoot routing
  • Bandwidth Management (BWM): Set bandwidth limits by user/IP to prevent hogging
  • Application Patrol: Create profiles that allow or block selected applications with specific actions
