[ATP/FLEX/FLEX H] What is the maximum number of DHCP Pool supported on Nebula firewall?

HienDang

I saw Zyxel have limit maximum number of Static DHCP table supported on Nebula USG/ATP firewall.

Firstly, what is the maximum number of Static DHCP table supported on Nebula USG_FLEX_H series? I still didn't see USG_FLEX_H on nebula to add, when will Nebula support to add?

Secondly, What is the maximum number of DHCP IP Pool supported on Nebula firewall USG/ATP/FlexH?

Wait, I thought Nebula Native Mode was supposed to come out by the end of 2024. What happened?

Hi @Dylan96

Nebula Native Mode is designed to simplify the deployment of Nebula firewalls (USG FLEX/ATP series) on the cloud. However, for the USG FLEX H series firewall, it will be introduced in a hybrid mode, not Nebula Native Mode. This hybrid mode allows configuration through both the Nebula Control Center (NCC) and locally, which is different from the previous firewall model.

With the latest uOS 1.30 release, the USG FLEX H series already supports some Nebula features, including:

• Nebula Topology
• Nebula Security Profile Sync
• Nebula Site-wide Device Status
• Nebula Site-wide Event Log

You can find more details in the release note:

USG FLEX H Series - V1.30 Patch 0 Firmware Release

To ensure seamless integration with Nebula, we're continually working to enable more features, so additional development is necessary. The full functionality is expected by 2025, stay tuned to our https://community.zyxel.com/en/categories/nebula-news-and-new-release .
