        It seems not much :) Read again the article: Q.3 - A.4

        How is the rp_filter protection set?:

/proc/sys/net/ipv4/conf/all/rp_filter
/proc/sys/net/ipv4/conf/eth0/rp_filter

        Why the packets don't come to eth1? It seems eth0/rp_filter=0
and then there is a ipchains restriction on eth0 not to allow the
client packets. The best solution is when using the internal and the
external card in same hub to enable the rp_filter protection on
all interfaces. Then you don't need ipchains rules in eth0.

        The requests are dropped from director.

        I don't understand the previous line. What you mean? I don't see
any packets to leave the director. "served" == "received from" ?
