Correct. You are still sending all the packets *to* the same place. > In fact, all the packet sent from two socket is go out by one > network adapter? Yes, of course. Why would the kernel send traffic to a destination out an interface that doesn't go to that destination? Suppose you have two interfaces, 1.2.3.4/8 and 10.2.3.4/8, if you are sending a packet *to* 1.2.4.5, it will go out the first interface. This applies whether the source address is 1.2.3.4 or 10.2.3.4. By default, the kernel routes traffic based on where it is going, not which interface address it came from.
