You're only allowed a single default route in a generic setting. By having two avenues to the Internet, you're essentially indicating that you need two, which you won't be able to do. Now, you may be able to leverage RRAS and configure the box as an OSPF router but I don't know if you can run ISA on top of such a configuration and if you can I don't know what might be able to be done to get ISA to play nicely with OSPF in the way you want it.
