ISP Redundancy weird working

ISP Redundancy was activated on the gateway in Primary/Backup mode, but incoming traffic proceeds on one of the external interfaces and outgoing traffic goes from another external interface. I don't understand, why.

Note: the gateway is the only node of the cluster.

Outgoing will go out via the Default Gateway in Active/Standby Mode.   If in Load Sharing then Static NAT goes out via Default Gateway.    Hide NAT is Load Balanced.

 

Inbound Traffic will simply arrive at whatever DNS resolves the name too and if that is the Standby Line then the inbound comes via the Standby Line.

Personally not a fan, either needs working on to make a worthwhile solution or consigning to bin and removing.
