Lots of people have the same issue, but I cant fix mine.
I tried the TTL hack, didnt make a difference. I see the ISP allocating me the IP address, they send an offer and then it does nothing.
I have dhcp-client under the Ethernet Gig0/0/0, I have enabled all services and protocols under the untrust security zone
Here is some debug, does anyone know whats going on? Im running 12.3 X48, latest on this box.
