We have a test environment which mimics our enterprise network security design. In this test environment my team and I would like to bypass our DMZ entirely. This seems easily enough done by simply changing the default route on our internal ASA (5510). The problem is that when using ASDM-IDM when I remove the old default route and create a new one it consistently will error out saying that there's a routing conflict. I'm not sure if this is a common mistake or if there is any guidance that you guys/gals can supply.
My next step is to manually change the default route via the console, but even if that works, I would still like to resolve this problem so we can use the GUI in the future.
Please let me know if there are any questions. Keep in mind that I have configured ASAs before and the current configuration is working correctly (its just points to a different gateway than we would like now). Also, i have double checked the routing on both the ASA and the device that the bypass (intended default route that is not working) is feeding to.
Additionally, I may need to look into version information.
