    Hi @Asgatlat,

    After checking, we confirm that IPv6 dual stack functionality will be included in the future firmware for the USG FLEX H series firewalls this year (2026).

    Thank you for your patience and understanding!

    Hi @Asgatlat,

    Thank you for reaching out to the Zyxel Community regarding IPv6 support for the USG FLEX H series.

    Currently, based on the available information, the USG FLEX H series documentation primarily highlights features related to IPv4 network management and security, such as DHCP relay, Dynamic DNS, and various security enhancements. While your previous ZyWALL 110 supported IPv6, the current public information for the USG FLEX H series does not explicitly mention IPv6 support in the feature lists.

    To provide you with the most accurate and up-to-date information, we need to gather some additional details.

    Information Collection Guide:

    • Device Model: Please confirm the specific model of your USG FLEX H series device (e.g., USG FLEX 100H, USG FLEX 200H).
    • Firmware Version: Provide the current firmware version running on your USG FLEX H series device. You can usually find this in the device's web interface.
    • Nebula Organization/Site Name (if applicable): If your USG FLEX H series device is registered with Zyxel Nebula Cloud Management, please provide your Organization and Site name. This will allow our support team to access your cloud environment configuration directly, significantly shortening troubleshooting time. You can enable Zyxel Support Access via Help > Support Request in the Nebula console.
