Set Up Wifi Bridge with DHCP Lease and separate Wifi Network

Hello,

I am using a GLinet AR750S.
I set up a wifi bridge to access my local network (over WAN port) from my ISP router (Fritzbox) with the main DHCP server. Any client connected to the wifi from my GLinet gets its ip address from my central router / DHCP server.

Now I wanted to create a separate wifi network with a separate SSID. That is connected to a new created interface lanlocal with a static address and dhcp server. This network should also be connected to my home network but keep its subnet. So if WAN is connected to a network with internet access I also want internet access within the subnet. If not, then there is only the local subnet. And here I struggle to get it work.

Here are my setting:

I have a minidlna service running. That shall be accessible from the subnet as well.

Any help highly appreciated.
