Hi Akash,

Can you paste your log of /etc/message, normally, you'll see something like
this:

"Apr 27 09:21:48 gd60 dnsmasq-dhcp[8872]: DHCPREQUEST(tapce4121ff-d6)
192.168.220.6 fa:16:3e:21:1f:58
"Apr 27 09:21:48 gd60 dnsmasq-dhcp[8872]: DHCPACK(tapce4121ff-d6)
192.168.220.6 fa:16:3e:21:1f:58 host-192-168-220-6
"Apr 27 21:21:48 gd60 dnsmasq-dhcp[8872]: DHCPREQUEST(tapce4121ff-d6)
192.168.220.6 fa:16:3e:21:1f:58
"Apr 27 21:21:48 gd60 dnsmasq-dhcp[8872]: DHCPACK(tapce4121ff-d6)
192.168.220.6 fa:16:3e:21:1f:58 host-192-168-220-6"

Besides, try to check iptables, you can use raw table to trace data path in
iptables.

Hope it helps,
Damon
