I enabled CONFIG_IP_TRANSPARENT_PROXY in kernel
and echo "1" >/proc/sys/net/ipv4/ip_dynaddr,
but I still loose the first packet.
linux/Documentation/networking/ip_dynaddr.txt:
IP dynamic address hack-port v0.03
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This stuff allows diald ONESHOT connections to get established by
dynamically changing packet source address (and socket's if local procs).
It is implemented for TCP diald-box connections(1) and IP_MASQuerading(2).
If enabled[*] and forwarding interface has changed:
1) Socket (and packet) source address is rewritten ON RETRANSMISSIONS
while in SYN_SENT state (diald-box processes).
2) Out-bounded MASQueraded source address changes ON OUTPUT (when
internal host does retransmission) until a packet from outside is
received by the tunnel.
This is specially helpful for auto dialup links (diald), where the
``actual'' outgoing address is unknown at the moment the link is
going up. So, the *same* (local AND masqueraded) connections requests that
bring the link up will be able to get established.
What else should I do?
