Indeed this is odd. A traffic cap from the DHCP server would be quite
helpful, if it's capable of that. If it's a linux box, then "tshark -i
eth0 -f 'udp port 67 or udp port 68' -w dhcpsniff.cap" should stuff full
packets into the designated file - alter the interface designation as
needed. The resulting file will be a binary capture that can subsequently
be opened and analyzed by tshark and wireshark, among other programs.
It'd be good if you could capture samples of:
A successful DHCP request from a PC.
The successful DHCP request from the FreeRunner.
A failed DHCP request from the same PC once the FR request has processed.
