Hi @rfranky 

Thanks for posting in our business forum.

You have tagged three models. Do you have the same issue on all three models? Firmware of them?

What are the Internet VLAN IDs? Do you have any identical VLAN IDs in the LAN?

Same issue with all omada routers. I only tagged three models becouse it's the maximum.

Firmware is the latest on all. Latest version of omada controller. 

Same vlan is not used in LAN anyway this shouldn't be a problem neither. 

 

 

 

So, on a single router, you cannot have set more than one identical VLAN ID.

And this issue/symptom happens to all three routers you have. Is this what you saying?

e.g. Setting the Internet VLAN 1000, already used on WAN1 and when you use it on WAN2, it fails and shows the error message, do I understand you correctly?

All of them are on the latest official firmware. Alright.

Exactly. 

I need to move your thread to the Router section.

About this issue, I will create a ticket for you. Please share the backup with me. Since you mentioned you have three routers, so I assume that you have this issue on multiple sites? If so, please share three backup files with me.

I will pass it to the test and dev team for further investigation.

We can't assign same VLAN ID on Multiple WAN Interfaces.
This should be fixed on Omada SDN Controller V5.12.7 as stated on release notes https://static.tp-link.com/upload/software/2023/202309/20230920/Linux%20Release%20Note.pdf but its NOT TRUE.
 

How's it going? Is it resolved with the V5.13 controller?

We manage more than 800 devices, we dont want to use beta software...

If so, please wait for the next stable release of the controller.
