Tuya / Lidl smart home devices don't work when connected to GS724Tv4
Hi All, Got a strange one here.... bought a Lidl smart home device and connected it via my switch. It's a rebadged Tuya device. When I search for the gateway, it eventually finds it, but it can...
DHCP on Netgear switch - No
Asus RT-AC88U with latest firmware - DHCP running there
Huawai Echolife HG612 modem
When I connect to RT-AC88U, the device works.
the Echolife HG612 also has an integrated router dhcp server.
Add in the asus and it can create a double nat.
Buy why would it make any difference? If I plug into the Asus port it works. The Asus is linked to the Netgear switch. If I plug into the Netgear switch it fails. What is the Netgear switch doing to the packets to stop it working?
Isn't double NATing a minefield. Would I set the HG to deliver just 1 IP in the pool - that of the Asus?
Would I set WAN-side address allocation as Normal or passthrough? At the moment, I have the Asus delivering x.x.x.4 to .250. It's on .3, with the HG612 as .1
This was how it was recommended on another board.
for some, double nat's doing cause issues.
others its nothing but issues. If its working and working fine, i'd leave it.
What Tuya devices is it?

Assume the PHY link on the port speed makes sense (same speed as on the Asus), the device does get an IP address assigned by DHCP (check the Asus router DHCP table/connected devices), check the switch ARP table for the device MAC address, ... have an eye for the IGMP Multicast settings for the VLAN in use. Allow IGMP multicast, and don't block unknown multicast.
The device is 100mbps. Asus is 1000mbps. Device gets assigned an address. Fing on my phone can find it.
Switching / Address table shows the device connected
I followed this to confgure IGMP Multicast

Still not working.
Block Unknown is disabled.
