Sergio can you suggest me such a switch with debugging port? Something you have tried maybe?....
My intention wasn't to change the WAN, but essentially the router, thinking it may block the traffic. I have followed the code extensively, I did tried to place various brakepoints, and to turn on the debugging functionality of LWIP, but it pointed me to nothing. Everything seemed absolutely normal. I am sure LWIP delivers the packet to the low-level driver, which in turn loads the data to the memory and starts the DMA engine of my MAC controller, but I can't figure out what happens next. As I stated I see no traffic, so I cannot be sure where the communication breaks. Seems I need a debugging device. *Fotis Panagiotopoulos* *--* *AMCO S.A.* 25 Amfiaraou st.
