I have a problem with +500byte ICMP packet, I am using ubuntu 16.04 and firewall inactive. When I try to send ping with this command
ping -s 500 192.168.1.127
ping is successfull, but when I try to send this
ping -s 580 192.168.1.8
ping reply didnt accept from computer but my 192.168.1.127 device send reply I see on network analyser. But computer not accept 500+ data. How can I solve this problem.
When I send the 500+ ping from computer my device replied just one time, and it shows me this error:
Expert Info (Error/Protocol): IPv4 total length exceeds packet length (578 bytes)

and I have bad checksum
What is the reason for the this error ? Pc connected point to point to my stm32+lwip device with ethernet interface.
