Which routing method has the highest precedence in a Sophos XG Firewall configuration?

The routing method with the highest precedence in a Sophos XG Firewall configuration is the health check. Health checks are utilized to monitor the status of a specific route and ensure that traffic is only sent through operational links. When enabled, if a primary route is down or failing based on the health check conditions, the firewall will automatically switch to a backup route. This dynamic capability is essential for ensuring high availability and reliability of network connections.

While static routes provide a defined path for packets and are generally prominent in routing decisions, health checks can override these routes to maintain connection integrity. VPN routes, though crucial for secure connections, do not supersede the checks made through health monitoring. The default route is a fallback mechanism that has the least precedence, as it only comes into play when no other more specific routes are applicable.

In essence, the health check method prioritizes real-time link availability, enabling the Sophos XG Firewall to make intelligent routing decisions that keep the network resilient and responsive, which is why it takes the highest precedence in the configuration.
