@BRYMA 

everything looks right, do you have screenshot of ER605 config?
and does the ER605 have access to the internet?
​

  @MR.S 

I have tried a couple of things in the ER605

  @MR.S 

The router is currently configured locally and internet is working.

Here is the other way I have tried the config:

  @BRYMA 

ok, cloud based controller is not nessesary. 

and your config is as it should be. I do a test to your port and all is accessible from internett.

how is your ER605 connected ? have router access to internett on wan interface?

I guess you are familiar with unifi :-) and omada is prety mutch the same when come to adopt device.

I am thinking that there must be something in my firewall that is not correct as far as port forwarding..

I have a unifi controller that is working just fine.

Here is the scenario

I have tried both the ER605 and the ER7206

When I plug them into the network where my Omada controller resides, they show up in devices and can be adopted. I do not have to configure the CONTROLLER INFORM URL

When I take them outside to another location, when I plug them in and go to the  Controller settings, and plugin the URL of our controller, the devices never show up in the controller for adoption.

I have the following ports forwarded on my firewall (same process I use for the UNIFI controller)

TCP: 8043,8088,8843,27217,29811,29812,29813,29814,29815,29816

UPD: 29810
