Accepted WAN/LAN auto-sensing
Background:
There is a typical network topology：
Some users might notice that, once the internet service fails, they are no longer able to access the NAS server from the local network.
The cause of this Phenomenon:
When internet service went down and the cable modem failed to provide an IP address for Main Deco, both Ethernet ports on the main Deco would work as WAN ports to detect internet connection. NAS would no longer obtain an IP address from Deco.
Why do we use WAN/LAN auto-sensing on Deco?
For the Deco Mesh system, normally, it would have more than 2 units, and each unit has at least 2 Ethernet ports; It would be time-consuming and confusing to find out which port should be connected to the ISP modem. And supposing that the WAN port is fixed, once this port is broken, the whole Mesh kit would be useless.
Recommended Solutions:
- Given that the issue arises only when the ISP modem fails to assign an IP address for the main Deco, once the cable modem recovers, the problem should be resolved. It is suggested to contact the ISP to restore the modem connection as a priority.
- The current workaround would be connecting the wired servers to the satellite Deco units instead of the main one.
- And we have also implemented enhancements on certain models, ensuring that the WAN port remains constant as long as the physical Ethernet connection between the modem and main Deco is unchanged, even when there is no internet service from the modem. Moreover, it is also planned to support manually fixing a specific Ethernet port as the WAN post on the Deco APP later.
The following models already support fixing the WAN port:
| Deco X80-5G Deco X50-5G Deco X20-4G Deco X50/X55_V1/V1.2 Deco X20/X60_V4 Deco X60_V3/3.2/V4.2 |

@TP-Link A lot of VPN routers have a configuration option for auto-sensing WAN/LAN connections. Auto-sensing means if you connect to your VPN via Ethernet, it will automatically prevent the internet from coming up on your LAN. It also prevents devices connected to your LAN from connecting to the internet via your VPN. If you don't have this option, you can manually disable the internet on your LAN: You should then set up a separate router for your VPN connections (if you're using multiple connections to different servers). You can connect it to your WAN port on your main router, which would be disabled in the above scenario, or use a port forwarding rule and a DMZ host where you want all of your SSL traffic to be forwarded. Make sure your DMZ host is not accessible from the outside world.

@Diabl0 I have the same issue.
My setup 3 Decos and NO other router worked for a few months and then it 'lost' the auto sensing on the main deco. Swapped routers,cable and reset all of them. No luck. Eventually I had to buy another router with a 'dedicated' WAN port to add it before the first / main deco.

This solution is not acceptable!!! I spend lot of money on my deco mesh system to find out i need another router, because you cannot add simple option to designate port role (even as "advanced" option)?
Please fix this asap, or refund me for my two M9 and three M5 so I can chose more experienced mesh manufacturer
I can't even believe this is a real thing. I want my money back too becuase I have the exact same issue Wow @Janbez54
