The request from the mobile client takes the shortest route to the server. The
response from the server is first forwarded to the Home Router, because the
destination address is the internal network configured for the server on which
the Home Router resides. The router then patches the response with the mobile
client's actual address and forwards the packet to the mobile client. In this
topology, the response takes an inferior path to the mobile client because of
the extra hops taken.
In general, you should install the Home Router in the middle of the network
so that most clients are only a few hops away, as shown in Figure 8. The Home
Router should be located somewhere on the path between the file server and
the mobile clients.
