<div dir="ltr"><div dir="auto">Hey,<div dir="auto"><br></div><div dir="auto">If you are using standalone gateway hosts and compute nodes do not have access to external networks, I think it is expected that you can not bind a port from the external network to the VM.</div><div dir="auto">In this case access to the external network is done only through L3 routers.</div><div dir="auto"><br></div><div dir="auto">So the idea is the following:</div><div dir="auto">You attach only a private (geneve) networks to the VMs. Then, you create a neutron router, which acts as a gateway for the private network, and is attached to an external network as well. Then you create a floating IP from the external network and attach it to the port of the VM from the internal one. This way you make the external network routed via gateway hosts.</div><div dir="auto"><br></div><div>Also, regarding your original issue "The task includes an option with an undefined variable. The error was: list object has no element 1" - we had similar case in IRC yesterday, and James Denton has found the workaround there by defining the br-ex bridge instead of naming it as br-flat, here was his paste that worked out for the folk: <a href="https://paste.opendev.org/show/bjw3b5ncP6dbhj34ltJU/">https://paste.opendev.org/show/bjw3b5ncP6dbhj34ltJU/</a></div><div>He also found an issue in our logic that caused this issue and has proposed a patch for that:</div><div><a href="https://review.opendev.org/c/openstack/openstack-ansible-os_neutron/+/893924">https://review.opendev.org/c/openstack/openstack-ansible-os_neutron/+/893924</a><br></div></div>
