Tong, There's no magic, you must either advertise a route for 192.168.2.0/24 or the upstream router(s) must have a static route for the the 192.168.2.0/24 pointing to your router. One way around this issue is to configure NAT to overload the routers interface IP or use addresses in the same range as the routers' IP.

[7:39410] Dear friends, Can I ask you the following question? It is what I see in the book. The network diagram and the NAT router config are shown below. Basically, when a packet going from a inside host to a outside hosts. Its source IP will change from 10.1.1.X to 192.168.2.2 after the NAT router. When the packet reply back from outside hosts, the destination IP will be 192.168.2.2. But I don't understand how the packet know to route back to the NAT's serial 0? The IP of router's serial 0 is 172.16.2.1. Unless we add route entry on the outside hosts, but how can we have the control on the outside hosts?
