Wireless bridge - Bidirectional communication

Installing and Using OpenWrt Network and Wireless Configuration
1

Hello everyone. I really hope I post this on the right forum / thread.

I'm having some issues configuring my OpenWrt router, I spent the whole yesterday trying to make my wireless bridge work. I really hope I can find some help here, as I am not an network specialist :slight_smile: .

My netwrok setup looks like this:

  • x50is the main gateway and wifi AP
  • AC88U is the Bridge, used for wired clients.
  • Subnet: 192.168.1.0/24
  • EDIT: DHCP range: 192.168.1.101 - 192.168.1.199

My goal is to allow the bidirectional LAN communications. Also, if I am wired connected to the bridge, I want to be able to communicate with wired / wireless devices from x50. And if I am connected to the x50 (wireless), I want to communicate with the wired devices from Bridge.

After following this tutorial Setup LAN/WLAN Bridge with OpenWrt (LuCI) (updated) - Nerd Quickies I was able to set up the bridge mode.

Now, if I I use a device connected to the bridge (Wired Client 11), I can ping and communicate with the devices from x50. That's expected and wanted behavior.
On the other side, if I use a device connected to the x50 (Wireless Client 10), I cannot reach any devices connected to bridge. (Wireless Client 10 -> Wired Client 2/3 communication works tho)

My understanding is that all the devices, including bridge, should be visible in the DHCP leasing list of x50. Sadly, that's not the case. Internet works as expected either on bridge or on x50.

What I am doing wrong?
Is the Client Bridge Mode the right option?

Thank you all for reading this.

LATER EDIT:

  • My goal is to make the bridge clients be accessible to any device connected to x50.
  • On x50 all isolation is turned off.
  • Connected to bridge are devices with static IPs, the only exception is the Client 11.

You'd save yourself a lot of trouble if you'd run OpenWrt on both routers and use https://openwrt.org/docs/guide-user/network/wifi/wifiextenders/wds instead, relayd is a buggy kludge that can never work properly; a wire is always preferable though.

I know a wire to x50 would be the best and the easiest method, sadly it's not possible. I also cannot change the x50's os because it's still under warranty.
I know, the situation is not pink, i have to improvise a bit.
what's funny tho, every device connected to the bridge gets an ip, but I cannot see the device on the x50's end. I believe it's a dhcp problem (somehow)

If you can install static routes in the x50 you can set up symmetric routing. There the devices on the OpenWrt LAN will be in a separate subnet (e.g. 192.168.2.0) but they can be reached freely from either network.
