   Humm, not   really.  In fact   I'm planning to  configure  this new
gateway in this manner:

   
   -+--+--+--+--+--[gateway B]------[gateway A]----------> Internet
    |  |  |  |  |       |  
      domain of A       |
                        |
                   domain of B

   At a first glance, B is in the subnet of A. In fact this is
because we're planning  to replace A by  B in a  near future. So, I
only need B working as a gateway.

   Is this the only thing that is necessary?
 
Thanks.
