Client has a flakey ASP. They would like traffic to be directed to a failover server in the event of failure. I know you can do this with load balancers - have done so many times in the past with CSS.
But I was wondering if there might be a way to have NAT statements activate/deactivate based on status of IP SLA object tracking. e.g. if ip sla 1 is returning true nat 192.50.1.5/32 to 169.5.4.1. But if ip sla 1 is returning false - nat 192.60.1.5/32 to 150.150.150.5. NAT and IP SLA - two great technologies that could work great together?
