Firewall in Using winsock

Now I am thinking of developig one appplication in winsock which access multiple NICs to send and receive packets.Now i am facing some problems.This application needs to listen to all interfaces.How I can do this ?Pls give me some answer?

Well, you create a socket for each interface (i.e. you bind each socket to a different interface).

I don't know if there's other way to do it in Winsock.
