Hi all,

I have some doubts in selecting the interface to transfer packets and receive the packets.

--> Multiple interfaces :
--------------------

1) 0.0.0.0 --------> wild card address.
2) x.x.x.x --------> valid address.(192.168.1.156)
3) ff.ff.ff.ff --------> broad cast address.


1) If an socket is binded to 0.0.0.0 and its destination ip address is ff.ff.ff.ff

In order to transfer a packet, the packet should be transferred through all interfaces.(broadcasetd).

2) If an socket is binded to 0.0.0.0 and its destination ip address is x.x.x.x

Based on destination ip address an inetrface will be selected to transfer the packet.

Before receiving the packets, the selected interface is closed.
Now the received packets consists of destination ip address as closed interfaces ip address. Whether the received packets are valid or not.


Thanks in advance.........
