DHCP Persistance issues

Hi @JPMuldoon,

Could you please clarify whether the issue you are experiencing is that "after updating the DHCP settings on Nebula, the device still displays the old DHCP configuration," or that "user endpoints are still holding the IP addresses previously assigned by DHCP"?

Additionally, please help confirm the following questions and provide us with your answers:

1. What is the model of your firewall, and has it been updated to the latest firmware version? (If not, please update it to the latest version first.)
2. What information is displayed under Configuration status in [Site-wide] -> [Monitor] -> [Devices] -> [Firewall]?

Finally, if the problem persists and needs further investigation, please follow the instructions in the article below to enable Zyxel Support Access so we can remotely inspect your configuration:

And provide us with the following details:

1. Organization Name
2. Site Name

We will further assist you. Thank you!
