└─>IP: policy routing
In linux kernel since version 2.6.12  
Normally, a router decides what to do with a received packet based
solely on the packet's final destination address. If you say Y here,
the Linux router will also be able to take the packet's source
address into account. Furthermore, the TOS (Type-Of-Service) field
of the packet can be used for routing decisions as well.

If you need more information, see the Linux Advanced
Routing and Traffic Control documentation at

If unsure, say N.
