I read about redundancy but what i need is different. I have here in the office a cisco router belong to the ISP. I have a backup link connected to the second WAN port of this router and only one link going in my ASA. So when there is a problem with the primary the backup take the primary function and in the both case i have the same public ip scope.
My issue is that the same ISP gave my scond different public ip scope which go out from the same router and is unsecure network. I want some how both public ip scope to be usable at the same time but going thrue the ASA. I dont know if you understand me. but this what i imagine.
