Do not use KEA DHCP after 50 days, I got a lot of problems and my devices did not come on the internet and also not got the right IPs.
So I had to switch back to the old ISC DHCP again.<\/p>\n\n\n\n


<\/p>\n\n\n\n

Warning – KEA DHCP is not working 100% in 23.09.1<\/h1>\n\n\n\n

With the release of pfSense+ 23.09, a significant transition in DHCP services is on the horizon. The move from the traditional ISC DHCP server to the modern KEA DHCP is not just a change; it’s an upgrade that brings several benefits and improvements.<\/p>\n\n\n\n

Why Switch to KEA DHCP?<\/h3>\n\n\n\n
    \n
  1. Deprecated ISC DHCP<\/strong>: The ISC DHCP server is now deprecated, signaling a shift towards more advanced and supported solutions like KEA.<\/li>\n\n\n\n
  2. Simple Transition Process<\/strong>: You can easily switch to KEA DHCP via System > Advanced > Networking<\/code> in the pfSense+ interface. A simple toggle from ISC DHCP to KEA DHCP is all it takes, maintaining the simplicity of the process.<\/li>\n\n\n\n
  3. No Reboot Required<\/strong>: Remarkably, switching to KEA DHCP doesn’t necessitate a system reboot. This feature ensures minimal disruption in network services.<\/li>\n<\/ol>\n\n\n\n

    Key Considerations for Migration<\/h3>\n\n\n\n
      \n
    1. Automatic Migration<\/strong>: pfSense+ is engineered to seamlessly migrate your existing DHCP settings to KEA DHCP, preserving configurations like IP ranges and reservations.<\/li>\n\n\n\n
    2. Manual Verification<\/strong>: It’s prudent to manually check that all settings have correctly transferred and KEA DHCP operates as expected.<\/li>\n\n\n\n
    3. Advanced Configurations<\/strong>: KEA DHCP offers more flexibility, which might necessitate some manual adjustments for complex configurations.<\/li>\n\n\n\n
    4. Documentation and Community Support<\/strong>: Leverage pfSense documentation and forums for any migration challenges or questions.<\/li>\n\n\n\n
    5. Backup Your Configuration<\/strong>: Always backup your current configuration before making significant changes like this.<\/li>\n<\/ol>\n\n\n\n

      Enhancements with KEA DHCP<\/h3>\n\n\n\n

      KEA DHCP is not just a replacement but an enhancement. It offers:<\/p>\n\n\n\n

        \n
      1. Unified Configuration<\/strong>: KEA integrates dynamic ranges and static mappings more cohesively.<\/li>\n\n\n\n
      2. Static Mappings in Dynamic Range<\/strong>: Static mappings can now coexist within the dynamic range, optimizing address space utilization.<\/li>\n\n\n\n
      3. Flexibility in Assignments<\/strong>: KEA allows dynamic and fixed address assignments within the same pool, offering greater flexibility.<\/li>\n\n\n\n
      4. Improved Management and Performance<\/strong>: Expect easier management and better performance with KEA, along with advanced features suitable for complex networks.<\/li>\n<\/ol>\n\n\n\n

        Post-Migration Steps<\/h3>\n\n\n\n

        After the migration:<\/p>\n\n\n\n

          \n
        1. Monitor Service Status<\/strong>: Check Status > Dashboard<\/code> to confirm KEA DHCP service is up and running.<\/li>\n\n\n\n
        2. Adjust Watchdog Settings<\/strong>: Update your service watchdog to monitor KEA DHCP instead of the old ISC service.<\/li>\n\n\n\n
        3. Review Notifications<\/strong>: Keep an eye on notifications for any alerts related to DHCP service.<\/li>\n<\/ol>\n\n\n\n

          In summary, the transition to KEA DHCP in pfSense+ 23.09 is a straightforward yet impactful change. It simplifies the DHCP management while offering improved performance and flexibility. Remember to verify settings post-migration and enjoy the new capabilities of your upgraded system!<\/p>\n\n\n\n
