                         255.255.255.255 ?

I think you want to send out a DHCP broadcast!? So why not use:
udp_connect(state->pcb, IP_ADDR_BROADCAST, DHCP_SERVER_PORT);

Please _don't_ change IP_ADDR_ANY!

btw, I'm glad to here that you are currently porting your
DHCP client to lwip - i'm very interested in that! Some times ago I
had a look at your DHCP(web-)sources - but it seems to much
work to me :-(

If you are looking for a tester - contact me!
