<div dir="ltr">Hi All,<div><br></div><div> I set up an openstack all-in-one environment with nova-network. I create a network <a href="http://172.16.10.0/24" target="_blank">172.16.10.0/24</a> which is the same as the real local area network. When I create an instances, The local area network can not work correctly sometimes.</div>
<div><br></div><div> I used arping command and found there were two gateway. One is producted by dnsmasq, and the other is physical gateway. I add ''dhcp-option:3,172.16.10.1" in dnsmasq.conf. But it seems that it doesn't work. </div>
<div><br></div><div> Is there any way to make the dnsmasq using the physical gateway?</div><div><br></div><div> Any advice is woulb really be appreciated.</div><div><br></div><div><br></div><div>Best regards</div>
