A TP-Link W8980 acts as a DHCP server on 192.168.0.0/24 subnet. This is also the only wifi access point.
A Zyxel USG 50 is connected to it through its 2 WAN ports and has static addresses 192.168.0.253 and 192.168.0.254
The Zyxel also acts as a DHCP server on 192.168.1.0/24 for the devices connected through its 4 LAN ports.
Is there any way to make the Zyxel the only DHCP server and create a unique 192.168.1.0/24 subnet, also for the devices connected to the TP-Link via wire or wifi?
I already tried to bridge WAN1 and LAN on the Zyxel and this way I can make the TP-Link to act as the only DHCP server, but this is not exactly what I want (and, furthermore, I lose the possibility of doing traffic balance on the 2 WAN ports of the Zyxel)
EDIT: I've made this simple image to better explain the situation. The desired result is that all the devices (wired or wifi) are on the same subnet

The typical configuration for a single DHCP serving multiple subnets is to setup the subnets as routed (usually they are VLANS) and activate DHCP-Relay (
helper-address
or what else) on the device(es) working as routers.If guess that the 192.168.1.0/24 network is behind NAT and not routed. Moreover I suppose that your network devices are "unmanaged" and don't support any of the needed features.
I think you cannot do that using your network equipment.
Maybe the guys at SuperUser, who deal with consumer level devices, could give you some tip.
EDIT:
Trying to guess, since I don't have any hands-on experience on your equipment:
I would move the Zyxel at the border of your network, using it as Internet Gateway (instead of the TP-Link) and use the TP-Link as a bare access point. Different configuration: it would be cleaner.
