WDS Client: all ok, but router not visible

Hello to everyone. I've i little problem with this simple configuration.

In origin there was only one big router AP in my local network area: (as the large part of the people in the planet earth).

Then a lot of clients has been connected to it.

Tomorrow two of them are too far from the AP and the signal is weak. So I placed an unused OpenWrt MR3220 on the network, follow the guide, step by step, https://openwrt.org/docs/guide-user/network/wifi/atheroswds to create a WDS.

On the main router ( I have just enabled WDS option.
On the client (Openwrt) with static address I have done the rest.

Now I have duplicated the SSID and amplified the wireless coverage. All works ok.
The clients devices see on unique SSID and (I suppose) they connect to the best signal (from Main AP or Client WDS).

The only strange problem is that i cannot connect to the router via Luci if my PC (for example is connected directly to the main AP ( If I'm linked to (Openwrt) via cable or wireless I can ping it and enter in Luci.

Where I'm wrong?

Another tips: if I ping from the ubiquiti router, it's ok; but in the same router the WDS Client seems not recognised!

This is my configuration on

Thanks to all.

Have you turned on WDS on your ubiquiti router?

Yes of course. But how I have explained I haven't any kind of problem with WDS. The only problem is related to some firewall settings, I think, that make it unreachable from a client on the same net but not phisically under itself.

Could you try different SSID for the WDS backhaul and the AP?

Firewall is normally set between different networks.

Yes of course. But now I have explained I haven't any kind of problem with WDS. The only problem is related to some firewall settings, I think, that make it unreachable from a client on the same net but not phisically under itself.

Did you solve this?

I'm asking because I had the same problem with the TP-LINK's stock firmware.

With OpenWRT I'm still unable to configure WDS successfully...

No I'm not able to solve it...

WDS work fine but I can't still connect to OpenWrt router.

The WDS configuration in the stock firmware is as simple as it can be, and I were unable to connect to the WDS client also, unless when directly hooked up on it.

I guess this can be a feature, and not an issue, but I can't say for sure.

I have checked right now but I can't find anything different.

With my smartphone I have just downloaded a generic app for LAN scanning and I found All The devices in my net except OpenWRT router...

The strange thing is that, following the first example, I can see (and others) but not .2

Even now that I am under the Wi-Fi created by the new TP Link router in stock firmware and wds client Mode.

WDS works at LAYER 2.

RELAYD (another way of creating a wireless bridge) works at LAYER 3. By using RELAYD you'll be able to access your router from anywhere in your LAN.

Check if this is good for you.

I'm at the opposite side: I'm using RELAYD right now, but struggling to make WDS works...

Thank you I'll check it later but I don't understand what is happening now.

This morning I connected my tablet directly under wifi generated by openWRT router ... Then I moved away and now I'm connected to another router on the same network and, surprise, I can can reach Luci on
If I try with pc it doesn't work...

Do you find something wrong here?
