lang=EN-US><FONT face="Times New Roman"> I am new to openstack. When
following the Install Guidance(kilo version) for Ubuntu, I was unable to
correctly configure the network. I followed the Guidance and set up 1 controller
node, 1 network node and 3 computing nodes. All configuration is almost the same
as the Guidance. However, if I set the gateway of management interface in
network node to 10.0.0.1 and change external interface to “dhcp” mode, which is
required by my external network environment, then I cannot ping other nodes from
network nodes. So I comment the gateway configuration and everything works fine.
But only network node can access to external network, other nodes are not able
to ping outside website. It will throw “unknown host” error. Can anyone help me
with this problem please? Thank you very much!!</FONT></SPAN></P>
