The question is not phrased very well but bear with me here, I have zero experience in network talk.

At home we have a D-link modem/router but my brother decided it would a good idea to turn on AP isolation meaning devices can’t talk to each other, which is not very good for me because I have a linux machine with all my media and bulk storage that I want offload storage and downloading things to so I dug up an old Huawei router that I want setup in the following way:

It (the Huawei box) connects to the main box (D-link) to get internet access and then my linux box and any other devices I might have connect to the Huawei box in a way that they would be able to talk to each other in a sort off subnet thing without ever talking to the D-link router meaning it would be inaccessible from my devices.

The D-link router is a DSL-2750U and it has 4 ports marked LAN and 1 marked WAN, the Huawei is an HG532s and has 4 marked LAN. I have zero control over the D-link router and full control on everything else.

It would much help if someone could guide me through setting this thing up.


This tutorial should help you do what you want. A quote from the article:

In this post, I am going to show you how you can add a second wireless router to the network that will be on a different subnet then the first router, but will still connect to the Internet using the main router as a gateway.

I believe that is what you want to do based on your explanation.

Turns out I had a TP-link repeater so I put that in the closet with the linux box, connected ethernet between them and setup the repeater with an ssid different from the main router. Now I can go back to doing nothing but watching pokemon :)
