But he must play with routing. Precisely he must, because he has misconfigured routes for the behavior he desires. His problem is about source address selection when trying to contact a given destination. If there is no specific source address specified, the kernel may legally use any source address, and this decision extends to ARP handling as well. It's totally illogical to say that it's easier for him to patch his kernel and reboot it than fix his route configuration. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
