WAN Failover lets you combine multiple internet connections to ensure stable cloud connectivity, even if one or more links fail. Continuously monitoring each WAN interface, Altostrat automatically reroutes traffic to a healthy link if the primary link goes down.

​
Key Benefits

  • Automatic Failover Traffic switches to a backup link within seconds of a primary link failure.
  • Link Monitoring Throughput and SNMP metrics are collected for real-time diagnostics.
  • Interface Prioritization Easily rearrange interfaces to set your preferred connection order.
  • Detailed Traffic Statistics Per-link metrics like latency, packet loss, and jitter help you troubleshoot.

​
Setting Up WAN Failover

1

Navigate to the WAN Failover Page

From your Altostrat dashboard, go to your site’s WAN Failover section.
2

Enable WAN Failover

On the WAN Failover overview, click Enable or Add to activate the service. If you see unconfigured interfaces, you can proceed to set them up next.
3

Configure Interfaces

Each WAN interface represents a network medium (e.g., DSL, fiber, LTE).
  • Click the gear icon next to WAN 1 to set an interface.
  • Provide details like gateway IP and physical/logical interface name.
  • Repeat for WAN 2, WAN 3, etc., if available.
4

Save & Prioritize

Once interfaces are configured, you can adjust their order to set which link is primary or backup.
Click Confirm Priority when done.

​
Best Practices

  • Monitor the Orchestration Log for link failover events.
  • Set Interface Priorities carefully to avoid redundant failovers.
  • Combine with Security Essentials to protect each WAN interface.
  • Test failover occasionally by unplugging or simulating link loss to confirm expected behavior.
