Multiwan Failover not working

[zickzack111]

Hello to all,

I have an OPNsense with 2 external internet Lines (DSL and LTE). These are each connected via a router and the OPNsense is connected to the Router with two /24 networks and a static IP.

I have set up an HA Wan which should automatically switch to LTE if the DSL connection fails. I set everything up as described in several instructions, including the photos of the configuration.

The Internet access also works perfectly, as does dialing in with the OPNVPN access via Wan

Now the DSL router failed yesterday, but there was no switch to LTE. I could neither resolve via DNS nor ping the google DNS server directly.

If, on the other hand, I enter the LTE Wan into the PC as a gateway in the FW rules, then I immediately get on the Internet.

What else do I have to consider here? Did I forget to add something special?

Many thanks for your help

greetings

You don't have to specify "Priority" if you don't want a LoadBalancing setup, so let it at the default setting. You also have to define the DNS Services with their corresponding gateways. Attached my (working) setup as screenshots.
