Hi Jens,

Thanks so much for your response! 

DHCPDiscoverOfferInform.pcap
<http://lwip.100.n7.nabble.com/file/t2316/DHCPDiscoverOfferInform.pcap>  

I've attached the Wireshark capture illustrating what happens when I send a
DHCP Discover. I get the Offer, and then get an inform, but I don't get a
request from my device - I can go into ip_input() and see the DHCPOffer
packet of length 342 in that function, so I know it's being processed. 

If the DHCP Inform that I'm seeing is completely independent of the DHCP
Discover/Offer, then the issue seems to be that the Offer is being ignored
by the client. Correct, 192.168.1.11 is my computer, and the Server on my
computer assigns with Offer assigns an IP of 192.168.1.100 to my client
which is the CC1352P1.
