It's very easy.  If yoy want to shape traffic from and to a computer, you 
need a dedicated linux box that you can put in front of that computer and 
that will act as a gateway.  1 NIC connected to that box and 1 NIC connected 
to the rest of the network.  You really needs this because you can only shape 
traffic that leaves the NIC.  When you have a dedicated box, you can shape on 
both NIC's and so can shape in both directions.  

So we only speak from shaping in one direction, but with 2 NIC's, you can 
shape in both directions.  Allot is doing the same thing.
