Hi, Use IP_RECVIF option. For IP_SENDIF look at http://lists.freebsd.org/pipermail/freebsd-net/2007-March/013510.html I used the patch on my embedded FreeBSD 9.0 boxes and it works fine. I modificated it slightly to match 9.0.

The Linux solution is SO_BINDTODEVICE, which according to socket(7): SO_BINDTODEVICE Bind this socket to a particular device like "eth0", as specified in the passed interface name. If the name is an empty string or the option length is zero, the socket device binding is removed. The passed option is a variable-length null-terminated interface name string with the maximum size of IFNAMSIZ. If a socket is bound to an interface, only packets received from that particular interface are processed by the socket. Note that this only works for some socket types, particularly AF_INET sockets. It is not supported for packet sockets (use normal [1]bind(2) there). This makes it possible to listen on selected interfaces for (broadcast) packets. FreeBSD currently doesn't implement this feature
