Hello

I'm trying to configure setup with 3 WAN ports, and want them to be prioritized by the order.

So everything should work through one port, and if it goes down - switch to the next one and so on,

but if previous port is back up - switch back to it.

It works fine for two WANs, since they are defined as "primary" and "backup" ("secondary") in the rule, but there is no "tertiary" 🤷‍♂️

Any ideas how to achieve this ?

May be you can set 2 Primary WAN and 1 Backup WAN, check Failover(Enable backup link when any primary WAN fails). in Mode.Hope that helps:)

But how to prioritize these two primary WANs in this case ? Which one will be actually used ?

Hi chuq,if Load Balance is enabled, traffic will also go first to the first WAN. Or you can set a Policy Routing rule to let traffic go to the first WAN you set up. 

And sorry for my mistake, Check Failover (Enable backup link when all primary WANs fail).

Seems like two primary wan setup doesn't work. I mean it works while both wans are online, but if one of them goes down - you gets random clients without internet

Have you try to set a Policy Routing rule to let all the traffic go through the first wan?

It's strange that it won't work when one wan down.

  @gatewait Policy routing seems to be ignored. I can't get all traffic to go through primary WAN. I have load balancing disabled and it still uses the secondary WAN/LAN1.
