2 network cards, sockets?

macshark · 01-29-2004, 08:53 AM

I have 2 network cards on my comp, and I intend to direct traffic from one network card to the other. Will be writing an application to handle this, but when i create the sockets, how am I able to specify which network card the socket will bind to? any suggestions?

thanks.

try doing it by MAC address that should be unique enough to differentiate between the two cards

i'm not trying to differentiate which socket is binded to which network card, What i would like to do is to specify that this socket A is binded to network card A, and socket B is binded to network card B.

Looking at the structure of the sockets, am i right that it can be specified in the struct sockaddr_in.in_addr ? which field in the sockets should be assigned?

thanks
