Hi Guys, I am writing a netfilter hooks module for applying kernel rules on incoming packets. I am implementing hook at NF_IP_PRE_ROUTING. >From my understanding, after sk_buff passing NF_IP_PRE_ROUTING hook enters into ip_forward (routing) path, which will determine whether packet is for local host, if not for local host, then routes to destination host based on IP header destination info through local host interface. My question is, if I modify sk_buff packet ip header info at NF_IP_PRE_ROUTING hook, with values of external host ip (destination host), therefore I think this packet will be routed to destination host from right source interface. Instead passing it to local host. Please correct my assumption. Or is anything more I should be doing. Because I am building a system to route the packets applying kernel rules. thanks in advance. -- Regards, Sri. -- To unsubscribe from this list: send the line "unsubscribe linux-newbie" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.linux-learn.org/faqs
