No actually that's the packets after they have been redirected. A packet enter the machine at one interface, is redirected, exits the machine and enter it again at a 3rd interface where the TCP server is listening. Thats the packet at the entry of the 3rd interface. OK, I'll do more testing to try to identify something. Thanks, olivier
