"Static" means that the routes are not forgotten when the system removes an interface because the gateway is not working. But the problem remains: how to handle this in iptables MASQ/SNAT commands? One can postulate that if the interface is removed because the gateway is dead, then the MASQ command will use the source related to the other gateway. However, the question now is: how to force the system to use the source address related to the "fast" gateway under normal operation while allowing a failover to the the slow gateway?
