Hi, sorry for no feedback, i've been doing more and more test and after enabled the dnsmasq log i found the error which i'm not longer sure if is related to having duplicated entries
dnsmasq-dhcp[21231]: 0 DHCPRELEASE(tap8ecf66b6-72) 192.168.111.24 fa:16:3e:72:04:82 unknown lease Looking around it seems i'm hitting this bug [1] but not clear from the description what was the problem on dnsmasp 2.59 (which comes wiht Fuel 5.1) Any ideas?
