I'm trying to determine if its possible to load balance across multiple ASAs that are on different subnets. We are planning to have two devices in our south data center and two in the north data center. we would like to have one virtual IP that outside users will connect to and have it load balanced across the four devices. According to the docs I've seen the load balancing appears to only be possible if the devices are on the same subnet. Our data centers are connected via fiber so there is a low-latency connection between the two facilities.
I have this problem too.
