I use static routes all the time. Its really simple, lets say your astaro has 2 interfaces 192.168.1.xx internal and 4.2.2.x External. But you also have a LAN/remote office with IP addresses 10.0.0.x that can be accessed via internal LAN using another router. In this case you will define a static route in astaro to route all the 10.0.0.x traffic to the internal LAN router otherwise all your packets will be forwarded to the external NIC and the destination will be unreachable.
Policy routing is just a little more control over the above concept allowing you to fine tune services etc. but I have never used it personally.

more examples are Welcome ,more usage scenario are also welcome ,i have 1 wiresless router how i can use using this feature (does it make sense if i am planning for ) i will route all wireless traffic to Nintendo dsi and using my astaro box (am i wrong ?)
The Wikipedia article on static routing links to a PDF file published by IBM titled "TCP/IP Tutorial and Technical Overview (IBM RedBooks Series)", where the topic of "Static Routing" is described on page 175 (Section 5.2.1).
