Hello Jan, thank you for your answer..I have inserted rt_loopback module. That's ok. After that, on my windows box, I can ping : 151.157.3.3 (which is my default gateway) 151.157.3.4 152.157.1.1 152.157.1.2 But there is a problem.. In fact, when I ping 152.157.1.2, my board responds but not the destination host.. ping request are never sent to the destination box.. So how can I do for forwarding packets to the destination box?
How did you check that there is no packet leaving rteth2? Does RTnet report something to the kernel console?
Have you got any idea about my problem? My configuration is the following : # rtrouteHost Routing Table Hash Destination HW Address Device 00 0.0.0.0 00:00:00:00:00:00 rtlo 00 151.157.1.128 00:0F:B5:42:73:4A rteth0 =====> input interface 1 01 127.0.0.1 00:00:00:00:00:00 rtlo 01 152.157.1.1 00:00:00:00:00:00 rtlo02 152.157.1.2 00:30:64:02:DC:1A rteth2 ====> output interface
That looks OK (if rteth2 is interface 4 in the figure below).
03 151.157.3.3 00:00:00:00:00:00 rtlo
04 151.157.3.4 00:00:00:00:00:00 rtlo

Sorry, no idea right now except that you should try to answer my questions above, maybe they will point you to the reason.
