Hi,

The issue has been resolved by upgrading new lwiP stack. But did some tweak in ip_route function to achieve.

    /* is the netif up, does it have a link and a valid address? */

    if (netif_is_up(netif) && netif_is_link_up(netif) && !ip4_addr_isany_val(*netif_ip4_addr(netif))) {

      /* network mask matches? */

return netif;

   #ifdef __NETMASK_COMPARE__  

 if (ip4_addr_netcmp(dest, netif_ip4_addr(netif), netif_ip4_netmask(netif))) {

        /* return netif on which to forward IP packet */

        return netif;

      }

#endif

Could you please suggest any better way for this ?

Hi,

The situation recreated , 

Now we are using one CISCO router.

1. LAPTOP is connected to CISCO router WAN port and  and lwIP device connected to LAN port of the router.

NCS(lwIP device) details

10.236.155.24

255.255.255.224

10.236.155.1

LAPTOP

10.236.26.180

255.255.255.192

10.236.26.129

In the above situation another one ethernet to serial module is working. But lwIP device not working.

2. LAPTOP is connected to CISCO router LAN port and  and lwIP device connected to WAN port of the router.

   Now the lwIP device is working fine

Follow-up Comment #7, bug #54914 (project lwip):

Hmm, ok, if it's really like that, it can't work...

Now I'm confused :-/
