Hello,
Use LWIP_RAW = 1 and raw_recv to install a hook to see packets before the stack does (in ip_input). You can return non-0 to stop lwIP from further processing of the packet.

Hi all, In my application, I have both TCP and UDP communication, lwip + freeRTOS (AVR32 project). If I rely on the thread on freeRTOS, I guess I can see UDP packets in the order of several ms based on the CPU loads. I'd like to find the quickest way to pre-examine any UDP packet (I don't care about UDP or other packets), where is the best place to hook such a piece of codes to eaversdrop? Any suggestion? Thanks, Chen
