I am trying to set up isp failover using a asa 5505 using cable internet and a dsl line.
I have my tracking and routes set up correctly i believe. I verified that the default route changes when the primary goes down. I followed these instructions from cisco: http://www.cisco.com/en/US/products/hw/vpndevc/ps2030/products_configuration_example09186a00806e880b.shtml#asdm
The problem is, i dont see any way to setup a backup configuration for dynamic NAT. ASDM does not let me add a second dynamic nat rule on the inside interface.
How do i get this to NAT correctly when it fails over?
