Could you bind() it to one card by its address before connecting? Or 
changing the default routes' metrics? The card with a lower metric will 
be selected first.

Assuming that you have card 1 with address 192.168.1.2
Then you should
endpoint ep{ ip::make_address("192.168.1.2"), 0 };
socket.bind(ep);
