hello,
I would like to submit an issue I encounter with the Following setup I have put in place in my home network.
In summary I am facing some kind of Connectivity routing issue between 2 clients connected via an asus RT-BE92U (wired) and some esp32 based devices (Shelly, esphome, …) connected via the Zenwifi BD4 mesh solution.
here is the topology:
- Main router rt-be92u configured with DHCP and network 192.168.1.1 and subnet 255.255.254.0 (so 192.168.0.1 until 192.168.1.254)
- WAN 10g is connected to modem (modem is bridge mode)
- LAN/WAN1 of router connected to my main PC with fixed ip
- LAN2/3 connected to switches to distribute amongst all home devices
- lan4 connected to BD4, 3 pack zenwifi solution, with a wired backhaul (so lan4 to lan1 of bd4 node1, then LAN2 of mesh node1 to lan1 of node2 bd4, then lan2 to lan1 of node3 bd4)
- BD4 mesh devices have been configured with ethernet backhaul setting, and with priority of LAN1 to force them to use ethernet
- Proxmox server is running with homeassistant vm on same subnet (wired).
- main wifi is configured with same subnet
The problem encountered is that when setting this up, the AI mesh is perfectly recognized, devices are connecting to the zenwifi mesh and they all have access to internet.
However, I run into issue when homeassistant (or any other host behind proxmox, including proxmox itself) tries to connect locally from a device connected to one BD4 mesh node.
if I try to connect from my main pc to the wifi esp32 devices, no issue.
if home assistant tries to connect to the same devices, there is no Connectivity at all (ping or http).
if I try to connect from internet to the devices it also works
Only local to local connectivty seems broken (for example 192.168.1.50 to 192.168.1.101)
IF i force the esp32 to use the aimesh of the main router (and not the BD4), then the Connectivity is restored…
This lead me to Believe there is an issue when using BD4 mesh, coupled with router BE92u.
I performed the Following change :
- switched from full ethernet backhaul to normal mode, with manual priority of each port on the BD4, no change
- switched from daisy chain Connectivity (from one BD4 node to the other), towards star-like Connectivity, using ethernet from the main router to each BD4 nodes individually (no change)
However, when I completely deactivated the backhaul ethernet to force using the 5ghz wifi, everything is working as expected… I can fully connect from each devices to other ones in the subnet…
this scenario was tested several times, and the result was the same, enabling the ethernet backhaul cuts the Connectivity between esp32 device and proxmox VM HA…
Last note:
I swapped the connection between LAN1 and LAN4 of the router : (lan1 beeing the BD4 ethernet backhaul and lan4 my home pc)
there I got the Following result :
- BD4 mesh is not able to connect to homeassistant and proxmox server, no issue
- my home pc seems to be the only one that is now not able to connect to other local ip's in same network (so no wifi involved). no able to connect to wifi esp32 or proxmox server.
- my first thought was that is was then not related to BD4 wifi mesh, BUT again, as soon I reverted to 5ghz backhaul, I was able to connect to all my devices !
my main clue is now that there is Something fishy with the ethernet backhaul somehow between this router and the BD4... so any experience is welcome ;-)
thanks again for your time reading all this, I am very curious about other things to try to find out what is happening here...
