Been looking at this image of the packet flow in linux: http://jengelh.medozas.de/images/nf-packet-flow.png In relation to this I have the following question: When does rp_filter happen? Is it part of the box named "routing decision", i.e. after iptables PREROUTING? Or some other place? /Oskar -- To unsubscribe from this list: send the line "unsubscribe netfilter" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
