Also, what does one subnet mean?

A. Using the same IP prefix on two different networks (ie. ethernet  
broadcast domains) with an interface in to each, or B. running two  
interfaces in to the same network (ie. ethernet broadcast domain).

In the case of A, are you re-using numbers on each side?
In the case of B, are you wanting both interfaces to have the same  
number(s)?
