Hi @karunadakandapatil.

By default, LoxiLB clears all rules upon restarting and boots up with a clean state. If you want to persist your rules, please save them using the loxicmd save -a command. If you want to save firewall rule only, then use the loxicmd save --firewall command.

Hi @inhogog2 ,

When i execute , i see that loxicmd save --firewall save the firewall rules to file in /tmp directory. Then i deleted the loxilb pod to see if it comes back up with saved firewall rules .. But it didnot ..

Hi @karunadakandapatil, since this doesn't seem to be a bug, I've updated the label to help wanted.

To clarify, when you run the command I mentioned earlier, the configuration files are saved in the /etc/loxilb/ directory, not in /tmp.

To persist this data in a Kubernetes environment, I highly recommend using a PVC (PersistentVolumeClaim) to mount that specific directory.

Please refer to this https://kubernetes.io/docs/concepts/storage/persistent-volumes/
