Question: Why H firewall revert WAN configuration changes after applying a static IP?
Answer:
This behavior occurs due to an automatic configuration recovery feature. To prevent H firewall from reverting WAN configuration changes, particularly when setting a static IP that temporarily disrupts internet connectivity, you need to enable a specific setting.

Solution Steps:
Access the Local Web GUI of H firewall.
Navigate to Network > Interface.
Edit the relevant WAN interface.
Enable the option "Change to a different ISP".
Enabling this option will allow the firewall to retain the new WAN configuration without automatically reverting it.
