I want to setup DHCP server function on one of the LAN interface on the ATP500 device (firmware version being "V5.39(ABFU.1) / 2024-11-16 03:14:26"). After entering the parameters of : DHCP (server), IP pool start address (192.168.1.130), pool size (10), First DNS server (ZyWALL), default router (ge4 IP) with rest parameters stay as default or without setting, click "OK", and then it prompts error of : CLI number (1), Error Number (-4027), Error Message ("DHCP Network Setting Conflict!"). Any help or pointer is highly appreciated.

    Is that range used in any other interface?

    Problem solved. It is because of some previous DHCP setting left behind that conflict with the new setup. This is invisible from the browser GUI, must use console port CLI to view and remove it.
