Hi, I tried to captured all the packets at NF_IP_PRE_ROUTING, made some changes to some of them, and invoked skb->dev->hard_start_xmit to send them out directly. However, the kernel crashed before I could get any printked information. If you have any idea of how to send the received packets out, please tell me. Thank you in advance. Best regards, Gu, Xinxing
