I just replaced a 506e running v.6.3 with a 515e running 7.0. The problem is that I have a dynamically assigned public IP but the default route doesn't automatically get set on reload. I have to login each time, do "show ip" and then use the "route outside" command to set it manually. Obviously, that's less than a desirable scenerio. On reload, there is a message saying something to the effect of "default route could not be removed". How can I get this to work?
