Routing behavior for requests coming in one interface but sourced from an IP on another interface

Say I have a load balancer with the following interfaces: VLAN 1 : 192.168.1.1/24 VLAN 2 : 192.168.2.1/24 VLAN 3 : 192.168.3.1/24

 

I have a virtual server on the same subnet as VLAN 1 with pool members on VLAN 2. Now say the hosts that exist on the same subnet as VLAN 3 have a gateway that is not the load balancer and the requests to the virtual server from these hosts are routed back around to the VLAN 1 interface through some other route.

 

Does the load balancer recognize that the source is on the same subnet as its VLAN 3 self-IP and route it directly out that interface or will it try to go back out the VLAN 1 interface?

 

Assume the default route points out the VLAN 1 interface and that source autonat is configured for the virtual server.

 

Thank you!
