Hi all

I tested a network camera, which seems work in this way:

it has a DHCP client inside, which starts on power on. But until an IP from DHCP server is available, it answers on fixed ip (i.e.

Can i do the same using lwip?

I tried to bring up an interface with fixed IP and after start DHCP, but it doesn't work: i didn't receive a new ip address from DHCP server.

I saw DHCP traffic using wireshark: in normal situation, DHCP client sends packet from to broadcast, and the server answers, in my situation i have DHCP request from to broadcast...
i suppose this could be the problem

Any idea??
