@Ayog Strange issues, I haven't pushed mine as hard yet, but PPTP on mine can't be turned off a few days after receiving the 1.1.1.1 update. Are you experiencing this as well?

@Ayog 

Did you every figure anything out on this? I noticed this same issue today on my network when my primary WAN failed and it wouldn't failover. My Primary WAN is is going through some maintenance over the next few weeks so I made my backup WAN my primary WAN, and set up some policy based routing and static routes to still route certain traffic out the old primary WAN, and I noticed I could not get any traffic to go.

I have the ER605 adopted into the controller. Wondering if the controller is crippling this? Maybe stand alone would be better?

Load Balancing on these routers doesn't mean that the router is examining your WAN internet bandwidth, it can only detect whether it's online or offline, with a simple ping function. You are the one that has to define the bandwidth for each WAN ports and then the router will distribute the traffic according to your definition. If a WAN port gets slower but still responds to ping, it won't change the load balancing ratio for you, it just can't do it.

Imagine, the router should run speedtest continuously to be able to correspond the actual bandwidth ratio, that's unrealistic.

You missunderstood this feature. It's about the ratio based on the given stable bandwidth difference and not to solve your unstable connection issue.

To be fair, I also had problem when I connected a relatively fast LTE router to a WAN port and another internet service to another WAN and when mobilenet slowed down significantly, the R605 kept sending traffic through it as if it were running fast. Because it wasn't offline in theory but in reality it was practically hardly accessible when too much traffic was forced through it. It was an embarracing disaster. I gave up using mobile internet in that mix, it's unreliable anyway (promising in some time and dissappointing in other), mobile providers use whatever algorithm they want to limit bandwidth rapsodically to deal with higher demand.

About the routing:

It actually works. When I had problem with that WAN port, I had to send all traffic to the other and configure my computer exclusively to get access to the internet via that problematic WAN port, to be able to test it and the router did it correctly.

You have to create an IPgroup with the devices in that IP range first and then a routing policy for that IPgroup to send them to the specific WAN port. Then create another policy the send all lan to the other wan port.

I could even do a policy routing based on the different MAC addresses of my computer's network cards. If I connected via wifi, it sent traffic through a specific WAN port and when I connected via LAN port, it went through the other WAN.
