They shouldn't be on the same subnet in most cases.  Keep IB on its own 
subnet.  What are your subnet masks?

What we usually do when we have a set of mixed nets is something like this:

eth:  10.100.0.0/16
IB:   10.200.0.0/16

this allows us to keep the traffic easily and obviously separate, and 
not set up strange routing bits.
