Route single internal IP out 2nd ISP (ASA 5510)

Cannot get a static route to work for a single IP to go out of failover ISP gateway, we have tried just about every method of the static command we can think of as well as adding lower metric route's for single IP, etc... no luck, traffic always goes out default gateway, not secondary.   Here is current setup:

global (outside) 10 interface

global (MIConnection) 10 interface

nat (inside) 10 0.0.0.0 0.0.0.0

nat (wguest) 10 10.10.1.0 255.255.255.0

nat (woffice) 10 10.11.1.0 255.255.255.0

route MIConnection 0.0.0.0 0.0.0.0 24.224.90.1 2 track 1

route outside 0.0.0.0 0.0.0.0 64.132.99.1 10

Route single internal IP out 2nd ISP (ASA 5510)

Hi,

If you want to have connections towards a specific destination IP address use the other ISP interface then you have to configure a specific static route for that destination IP address.

The above configuration only holds 2 default routes atleast and naturally only one of them is used at a given time.

On the other hand if you had a Static Default Route and a Specific Static Route it should work so that the Specific Static Routes IP address would be found behind the other ISP while all other traffic would follow the ISP holding the Static Default Route.

For example

route ISP-1 0.0.0.0 0.0.0.0 1.1.1.1

route ISP-2 100.0.0.0 255.0.0.0 2.2.2.2

This should result in the network 100.0.0.0/8 routed towards the ISP-2 link while others would be found behind ISP-1.
