Apologies for not responding before, I was making more tests. I tested (again) with explicit mac-addr (4 ones) instead of using wildcards ... and it worked fine, for example:
May 18 17:07:04 cinemateka dnsmasq-dhcp[2497]: 1123473942 DHCPREQUEST(eth0) > 192.168.0.249 a4:50:46:d0:4d:e3 > May 18 17:07:04 cinemateka dnsmasq-dhcp[2497]: abandoning lease to > 96:8d:d4:d0:4d:e3 of 192.168.0.249 > May 18 17:07:04 cinemateka dnsmasq-dhcp[2497]: 1123473942 tags: mobile, > known, eth0 > May 18 17:07:04 cinemateka dnsmasq-dhcp[2497]: 1123473942 DHCPACK(eth0) > 192.168.0.249 a4:50:46:d0:4d:e3 xiaomi-a2 but I am not crazy and I know it failed, so what did I do? I downgraded dnsmasq version to 2.75 that was the one I had initially, and: May 19 09:05:16 cinemateka dnsmasq-dhcp[2212]: 2882342319 DHCPREQUEST(eth0) > 192.168.0.249 96:8d:d4:d0:4d:e3 > May 19 09:05:16 cinemateka dnsmasq-dhcp[2212]: 2882342319 DHCPNAK(eth0) > 192.168.0.249 96:8d:d4:d0:4d:e3 address in use > May 19 09:05:16 cinemateka dnsmasq-dhcp[2212]: 2882342319 broadcast > response Same configuration file (except the line "dhcp-ignore-clid" I had to comment, because that option is not valid in 2.75). So I don't know why, my 2.75 is not working, and I don't know why (it was a feature introduced in 2.47 I think). I have to say the 2.85 version I am running was compiled in my box, cloning the sources from git:// thekelleys.org.uk/dnsmasq.git, while 2.75 was installed from binaries using the repository of the Alt-F project. No idea if this is relevant. The good point is that it is working now and whatever happened it is not happening now. Thanks a lot everybody for the ideas and questions that forces me to investigate further.
