Hey Mario, this looks like your communication partner doesn’t have the right IP set as target:
ip_input: iphdr->dest 0xFFFFFEA9 netif->ip_addr 0x4301A8C0 (0xFFFEA9, 0x1A8C0, 0xFF000000) ip_input: packet not for us. the destination IP is: 0xFFFFFEA9, which is 169.254.255.255 (that is the AutoIP range that e.g. windows assigns if it doesn’t get an IP from dhcp). And that is certainly “not a packet for us” since your netif has 192.168.1.67 with a netmask of 255.255.255.0 Does that help? Otherwise, create a wireshark capture of the traffic. Kind regards, Fabian
