You can create a second set of virtual IPs, start a listener and configure listener_networks in the database to allow connection via a different network subnet or segment. However, SCAN needs to be resolved via DNS so unless there is a route to the subnet of the SCAN via the client's gateway (and also the gateway set for the cluster), you cannot connect via SCAN since its IPs won't have a route.
