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 ?
That was a good advice, I only used the window cmd to ping those devices. I'll try Wireshark tomorrow! By the way, ping IP by using cmd that have to send ICMP packets, isn't it?? In order to trace packet flow, l print some message log with SPI and Teraterm. 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 OK, I see, I will try to think what you say, thanks for your tips. -- View this message in context: http://lwip.100.n7.nabble.com/Lwip-with-two-ethernet-ports-tp24405p24433.html Sent from the lwip-users mailing list archive at Nabble.com. _______________________________________________ lwip-users mailing list [email protected] https://lists.nongnu.org/mailman/listinfo/lwip-users
