ASA static nat from the outside to 2 internal interfaces

I have an ASA5510 running 8.2 code and I have over 200 static nats from  the outside to the inside interface and that is how I expose our systems  to the Internet.  If this inside interface fails we also have a bypass  interface that also terminates on the internal network but I am not sure  how the nats will behave given they are statically mapped to the  inside.  how do i overcome this problem?

Hi,

You would need to create the same amount of nats for your backup interface as well, for eg:

static (inside,outside) 2.2.2.2 10.1.1.1

static (inside,backup) 1.1.1.1 10.1.1.1

Similarly you would need to create it for the rest of the statics as well, to provide redundancy to the network.

Hope that helps.

Thanks,

Varun
