i used lwip example in stm32cubef4 like to(udp echo server,tcp echo server,......).when i connect 2 stm32f407 eval boards as udp or tcp servers to ethernet hub switch and connect to pc as client my servers don't work correct.
pc(client)<----------><ethernet switch----->}{<--stm32f407 board as udp server1-->
}{<--stm32f407 board as udp server2-->
but the system work good when i disconnect one stm32f407 board from switch
pc(client)<----------><ethernet switch----->}{<--stm32f407 board as udp server1-->
why lwip lib don'twork with 2 servers in ethernet chain?
