Problem with Dual WAN after upgrade to 5.6.3

Hello from Austria,

I have a weired problem, maybe someone has a hint for me:

 

We're using a 92D:

 

On WAN1 is a broadband line with DHCP for the transport IP and a /29 subnet routed over this transport IP.

On WAN2 is a DSL with PPPoE authentication, I also get a transport IP and have a /29 subnet.

 

The guy who mostly managed the firewall has somehow configured a failover, so if WAN1 is down, all traffic gets divertet to WAN2. As he is no longer available, I cannot ask him, how exactly he has configured this, because there is no SDWAN config and also no link monitor configuration. I just realized, that it somehow worked.

Both Interfaces have the distance 5 and as both default gateways are aquired with DHCP, I cannot manage the priority.

 

Everything was fine until today I upgraded from 5.6.2 to 5.6.3. After the upgrade the default route is pointing to WAN2 and I have no idea how to switch back to WAN1. I tried to lower the distance to 1, but that didn't help.

 

In the routing monitor I see the trasport IP and the default gateway from WAN1. When tracerounting to the gateway-IP, it's reached in one hop.

 

And now I'm very clueless where to look next resp. what to do to get the traffic back to WAN1.

 

Any help highly appreciated.

 

Thanks a lot,

 

William

Hi ahmedsf,

 

thank you very much for your offer, but our company policy does not allow to give anyone access to the firewall, not even temporary or readonly. Maybe you do have a tipp for me, where to look?

 

Kind regards,

 

William

Hi William,

 

I can understand, can you send me the snapshot of the current policies?
