[lwip-users] DHCP and AutoIP - TCP doesnt work

[gregoryhouse]

Hi,

My device is configured using DHCP and AutoIP. I have enabled the following 
options:
LWIP_DHCP
LWIP_AUTOIP
LWIP_DHCP_AUTOIP_COOP

Network addresses set by the DHCP are correct and AutoIP also works well. 
Unfortunately TCP and ICMP aren't working. I've tried Ping and web server and 
there is no answers from device. If I change the IP assignment to STATIC or 
turn off autoip all applications work fine.

In init task I call:
netif_add(&lwip_netif, &ip_addr, &net_mask, &gw_addr, NULL, ethernetif_init, 
tcpip_input);
netif_set_default(&lwip_netif);
netif_set_status_callback(&lwip_netif, status_callback);
tcpip_init(NULL, NULL);

In tcpip_thread I call (through tcpip_callback):
dhcp_start(&lwip_netif);
autoip_start(&lwip_netif);

I attach a log captured during initialisation of the device. Enabled are 
DEBUG_DHCP, DEBUG_AUTOIP, DEBUG_ICMP.

Best regards.
