[lwip-users] DHCP and changing the MAC address |

Hello,
I have a manufacturing scenario where I need to change the
MAC address after DHCP has come up. My code will stop_dhcp
and then start_dhcp. If I initially zero out the ip address,
I get a response from my dhcp server and am up and running
however, when the code goes to change the listening pcbs
for any previously running services, no pcb local addresses
get changed to the new dhcp-assigned addressed because the
interface ip was set to zero and does not match the original
pcb's local address.
If I do not zero the ip address prior to asking for a new
dhcp address, (ask for a new dhcp address while I claim I
have an address) I get no response from my dhcp server. The
coarse timer simply keeps sending out requests every 10 seconds.
Going back and forth from DHCP-off and a static IP address
to DHCP-on performs perfectly.
Could anyone help on this issue?
Thanks in advance,
Tom Barker
