If you have an inside router
If you have an inside router, you can route between the management network, which can include both 
the ASA Management 0/0 and IPS Management 1/0 interfaces, and the ASA inside network. Be sure 
to also add a route on the ASA to reach the Management network through the inside router.
If you do not have an inside router
If you have only one inside network, then you cannot also have a separate management network, 
which would require an inside router to route between the networks. In this case, you can manage the 
ASA from the inside interface instead of the Management 0/0 interface. Because the IPS module is a 
separate device from the ASA, you can configure the IPS Management 1/0 address to be on the same 
network as the inside interface.
