   Hi,   
      
   the answer is unfortunately that it doesn't. The two ends have usually   
   to be in two different subnets. For some top-of-the-range routers fudges   
   can be made, but don't go there unless you have to. Be a coward and put   
   one of the LANs at 192.168.2.xxx for example.
