Peplink e50 needs to ignore down router

Hi

I have peplink e50 connected with 5 routers, if any one of them become internet down internet become disconnected from peplink.
is there a way to ignore that router if become internet down?!

Thanks

Is that a balance 50 you have?
You need to enable health checks on the WAN ports so an unhealthy WAN is marked red and unavailable, then you need an outbound policy that uses all wans in the right way to suit your needs.

When one wan fails, the rest will be used for traffic.
