[openstack-dev] Re?? [neutron]How to use external_net?

[????]

Thank you C??dric/ZZelle,
I have tried this way before, but it could not realize the connection between 
two networks belongs to different tenants. So the floatingIP comes from tenant 
A could not bind to VM from tenant B.
Do you have any suggestion about this?
Thanks.


YU

Hi,


You need a router to bind internal network(s) with external network.


Otherwise you cannot allocate a floating ip (on the external network) to VMs 
(on internal network(s)).


The doc[1] explains how to do it.

Hi all,
  I find that if setting the value of router:external=True for a 
net(example: neutron net-update netID --router:external=True)
  Users in other tenants could allocate floating IP from this net(example: 
neutron floatingip-create netID).
  But how could this floating IP bind to a VM created by the user from 
other tenants? The network is unreachable.
  Or do I misunderstand the function?


Thanks,
Yu

Hi,

I'm guessing tenant A is admin tenant.

Also, you can check the iptables NAT rules under router namespace in case
of ovs plugin.

You should find binding there.

Yatin
