I don't understand where this values came from? which would be the
normal values?

I tried connecting the modem directly to the server, without a switch
or any server that may cause any trouble. I got the same result, the
server receives DISCOVER packet. Chechinkg the log on debug, it seems
to send and OFFER (Sending DHCP-Offer of id 8e22cb4d from to but it doesn't, It's
verified that it does not send it.

What can I check, in order to find the problem?

Thanks for your interest.
