For more information, see In Fireware v12.0.2 and lower, modems are not dedicated external interfaces and do not appear as interfaces in the multi-WAN settings.

WAN that is down, daemons on the firewall will be unable to make outbound
that it can move connections off of a failing gateway, but it cannot force them If you use dynamic routing, the route table includes dynamic routes.To see whether a specific route exists for a packetâs destination, the Firebox examines its route table from the top to the bottom of the list of routes. The Routing Table multi-WAN method uses ECMP to evenly distribute outgoing traffic When the primary interface is active again, the Firebox immediately starts to send all new connections through the primary external interface again.You control the action for the Firebox to take for existing connections; these connections can failback immediately, or continue to use the backup interface until the connection is complete.
This currently only works one-way, meaning This concept is similar to how software-defined networking implements virtualization technology to improve data center management and operation.. A key application of SD-WAN is to … Learn about SD-WAN with SDxCentral's SD-WAN definitions.
For example, if your ISP is asymmetrical and you set your bandwidth threshold based on a large TX rate, interface overflow will not be triggered by a high RX rate. See our If you use dynamic routing, the route table includes dynamic routes.To see whether a specific route exists for a packetâs destination, the Firebox examines its route table from the top to the bottom of the list of routes.
If all WAN interfaces have reached their bandwidth limit, the Firebox uses the ECMP (Equal Cost Multi-Path Protocol) routing algorithm to find the best path. When the traffic through that interface reaches the bandwidth threshold you have set for that interface, the Firebox starts to send traffic to the next external interface you have configured in your Interface Overflow configuration list. 2/11, and 1/11 of the total traffic flows through each of the three interfaces.Use the Interface Overflow method when you want to restrict the maximum bandwidth that each external interface uses. Multi-WAN failover and FireCluster are configured separately. Other external interfaces are backup interfaces, and you set the order for the Firebox to use the backup interfaces. The Firebox monitors the primary external interface. In pfSense, the Policy routing provides a powerful means of directing traffic to the appropriate For information about how to configure modem failover in Fireware v12.0.2 and lower, see In Fireware v12.5.4 or higher, failover is the default multi-WAN option.When you use the failover method to route traffic through the Firebox external interfaces, you select one external interface to be the primary external interface.
this setting, see Traffic exiting the firewall itself will use the default gateway unless a static across multiple external interfaces based on source and destination IP addresses, and based on the
Multi-WAN failover caused by a failed connection to a link monitor host does not trigger FireCluster failover.
The route table includes static routes that you configure on the device. When
rule can match. When you configure multiple external interfaces, you have several options to control which interface an outgoing packet uses. Specific hosts, subnets, protocols and more can be used to In an enterprise, a WAN may consist of connections to a company's headquarters, branch offices, colocation facilities, cloud services and other facilities. For information on changing If it goes down, the Firebox sends all traffic to the next external interface in its configuration. Use the Routing Table method when you want a quick and easy way to evenly distribute outgoing traffic among multiple external interfaces.When you configure multi-WAN with the Routing Table option, the Firebox looks at its internal route table to check for specific static or dynamic routing information for each connection.
