I have an OpenStack deployment using kolla-ansible with the Yoga version. Our network setup is provided in the attachment (network.jpg). The configuration file (globals.yml) and inventory (multinode) are also attached to this email. After the deployment steps, I try to run the script init-runonce to create the images and the networks by modifying the external network parameters according to our network setup. I am successful in launching instances from the horizon dashboard. However, the instances were not able to connect to the Internet. I have tried attaching the floating point IPs to the instance, where the IPs are successfully allocated from the range I have specified in the init-runonce script. When I launched the instance and tried to ping the external network, it failed. It will be very helpful if anyone can advise me to resolve this issue. I am currently using Ubuntu 20.04.05 LTS version on the controller and compute nodes.

Best regards,

Vincent
