Gateway always down [closed]
Hello All,
I'm having some problems to bring up the gateway on the public network. I've see other questions about it but nothing helped me, the network:router_gateway port is allways DOWN. I've a three node installation: compute, network and controller. This is the port status:
[root@neutron ~(keystone_admin)]# neutron router-port-list PublicRouter

The installation (packstack) enabled the IP forwarding:
[root@neutron ~(keystone_admin)]# sysctl net.ipv4.ip_forward
net.ipv4.ip_forward = 1

I thought that it was not normal :-(

dbaxps ( 2014-07-25 12:36:13 -0600 )editI thought it have to be active to allocate floating IP and access to the instances from the public network.
