Hi Simon,

Thank you very much for your reply. If you would be agree with adding LWIP_HOOK_ETHARP_GET_GW, do you agree with the following changes?

 

Adding LWIP_HOOK_ETHARP_GET_GW in HOOK section of opt.h and changing the following part of "etharp_output()".

 

{

#ifdef LWIP_HOOK_ETHARP_GET_GW 

    dst_addr = LWIP_HOOK_ETHARP_GET_GW(netif, ipaddr /* The IP address of the packet destination */ );

    if(!dst_addr) { /* no route to destination in routing table  */

#endif

       /* interface has default gateway? */

        if (!ip_addr_isany(&netif->gw)) {

          /* send to hardware address of default gateway IP address */

          dst_addr = &(netif->gw);

        /* no default gateway available */

        } else {

          /* no route to destination error (default gateway missing) */

          return ERR_RTE;

        }

#ifdef LWIP_HOOK_ETHARP_GET_GW 

    }

#endif

}
