ER605 V2 and Multi-WAN Failover configuration
I have the following topology:
Fiber ONT <--------> ER605 WAN
Netgear 4G LTE <--------> ER605 WAN/LAN1
ER605 LAN2 <--------> Router/Switch for rest of the house.
I have a software controller running on a PC.
My configuration is WAN primary on Fiber, with the 4G/LTE as failover only.
The 4G/LTE is a limited data plan, so it's use is metered, and I only intend to use it in the case of a failure on the Fiber, due to a cut or outage.
I have this set up correctly in the controller software, as best as I can tell. However it seems my ER605 is still sending traffic over the 4G/LTE link, as evidenced by the traffic counter incrementing in the LTE Modem's interface. We aren't talking a lot of traffic, but there really shouldn't be any.
I have tried creating a policy route that enforces traffic to the primary WAN and only go out to the failover in case of a failure, but this seems redundant, based on the defined settings of "Use Link Failover" in the other config panel.
Is this a bug or something? Is there a way to request a feature that this WAN link be left unused except only in case of failure? There's literally no need for the controller to be sending healthcheck pings, if that's what it's doing.
Hi, I just tested my local failover network and it works perfectly, how did you find the data also goes through the backup WAN?
How did you set up the Link Backup? Did you also set the online detection and the Echo server?
If the WAN still shows online even though it has been down, click the ER605 on the device list and go to Config----Advanced, set the Echo server to check the link.
Hello @Virgo
I'm using the software (PC) based controller, and it seems I have to set the echo server to one value which is applied to both WAN interfaces. My idea would have been for the ER605 to ping the gateway of this device, rather than an external address. This way, the Er605 would simply trust this unit to be online as long as the unit itself is reachable. But, I cannot specify a separate echo server per WAN link.
I can tell the ER605 is sending traffic out this device by two indicators: 1) Monthly LTE Usage: 0.59 GB used (that's all ping traffic) and the bottom, Session, 0.2MB which has incremented just after enabling the LTE modem. (I've been leaving it disconnected, and would failover to it manually to avoid sending constant pings out of it).
The desired operation would be:
WAN - send all traffic here unless it fails. Leave WAN/LAN1 in standby mode, and don't send any traffic there unless primary WAN fails.
The observed operation is currently:
ER605 is pinging out of both WAN and WAN/LAN1 constantly to confirm they are online.
Am I looking in the wrong place?
Thank you!
