To answer a ping to eth0 coming from eth1, lwIP has to actually route the response. Is it capable of doing that or will it send it to the gateway (which does not exist) ? Have run Wireshark on your PC and checked if your lwIP device is actually sending something ? Have you followed the packet flow inside your lwIP device ?
For the future: You won't be able to ping Device_2 from your PC unless: - Device_2 is configured to have Device_1 as its gateway to 192.168.190.0/24; otherwise it will send it to .254, which is... - Device_1 routes -- _______________________________________________ lwip-users mailing list lwip-users@nongnu.org https://lists.nongnu.org/mailman/listinfo/lwip-users
