Model: ER605 (TL-R605)  
Hardware Version: V2
Firmware Version: 2.2.6 and 2.30

Hi, I have many routers Mercusys MR50G connected to my ER605 using Omada.

They are all connected by WAN port.

In the routers I have the option to disable NAT in the WAN port, so the internal IP is passed to my ER605

This way I can manage to get Portal work for each client connected to my routers.

The problem: ER605 V2 firmware 2.2.6 and Omada 5.14.32 don't work at all

ER605 V2 firmware 2.30 works and Omada 5.15.24.18

But the lastest one is very buggy, its practically unusable.

  @MR.S 

Hi thanks for your answer

As I said before, I cannot use 5.15 because all the problems it has.

And I cannot want to disable NAT on my ER605, I disabled NAT in my Mercusys MR50G

With Omada 5.15 it work, with Omada 5.14 not.

I didn't get any communication with Omada older than 5.15;
