For some reason i am not able to ping from an instance to the subnet the controller and compute's are on. The network is pretty simple.

VM's/Instances: 10.10.2.0/24 Controller/Compute's: 10.10.1.0/24 The routers external gateway is 10.10.1.4 which I can ping from the instances. Ant help would be greatly appreciated.

  • Hi @schap, to get help you are going to have to give a little more information. Maybe draw your situation so that people get a picture of what you are trying to achieve. Normally it makes sense that you seperate your controller and compute's network from client subnets. – BakaKuna Mar 18 '21 at 14:59

    I understand that you have an external network that maps to 10.10.1.0/24. Can you add the output of `openstack network show NAMEOFYOUREXTERNALNETWORK` and `openstack subnet show NAMEOFYOUREXTERNALSUBNET` to the question? And how did you configure that external network? Please share your agent configuration (usually Linuxbridge agent or Openvswitch agent). – berndbausch Mar 19 '21 at 02:49
