How make LAN port leverage local DHCP of the GL-MT3000 / Beryl AX

Hi.

I would like to make the LAN port leverage local DHCP of the GL-MT3000 / Beryl AX.

Right now it keeps giving out an APIPA address of the WAN connection. Setting a static IP based on the network of the GL-MT3000 does not seem to be working either.

Ideally I want to have the GL-MT3000 and everything behind it separate from anything else on the network.

Thanks in advance.

Hi, may I ask if the devices connected to the router have not been assigned an IP address?
