@RBL Strange, I have almost same switch (ES205GP) and it upgraded without any problems, but as the message says, the switch must have access to the management port, do you have something blocking it?

@RBL As the message says, the switch must have access to the controller's management port. Is it a local site or a remote site? Is the switch on the same network as the controller?

@Fishy8 If you have adopted both routers into the same Omada controller you can install the new ER605v2 EA firmware 2.3.0 and use SD-WAN, you need a public IP on the HUB device and it can be dynamic,...

@IIIdefconIII disable port forward to 1195, you should not port forward when the OpenVPN server is on the Omada router.

@GRL but I see that the latest firmware must be used on routers, on the ER707-M2 I cannot change the default vlan port, nor can I disable the port on the router

@GRL yes that was a nice feature too. yes Omada is getting more configurable with each version :-)
