[lwip-users] fixed IP and DCHP on the same net interface?

[Piero 74]

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. 192.168.1.3)

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 0.0.0.0 to broadcast, and the server answers, in my situation i have DHCP request from 192.168.1.3 to broadcast...

i suppose this could be the problem

Any idea??

Thanks,

Piero
