bind() not working for outbound socket connections...

why is bind() not letting me specify a particular interface (on a multihomed system) to send socket messages thru?

i have a system with two ports, one is connected to a router that CAN see the internet and and one is connected to a router that CANNOT see the internet.

if i try to bind() a socket to the port that connects to the "dead" router, the system still autoroutes it through the good interface to get the message to the web server out on the internet. for most practical purposes, that feature rocks, but for my particular needs, i have to be sure that the messages are being routed out through a specific interface. if there is no good route to the destination address thru the chosen interface, then the subsequent connect() should fail (as opposed to looking for another route).

i **don't** want these particular messages autorouted thru any random interface.

please tell me how to either get bind() working or to do what i'm trying to do in some other way.

thanks.
