The appropriate configuration for emulating conventional stateless IP routing is a Forwarding (IP) virtual server using a FastL4 profile .

A Forwarding (IP) virtual server does not select an application-server pool in the normal load-balancing sense. Instead, BIG-IP forwards the packet toward the destination address originally specified by the client and uses the system ' s routing table to determine the serverside path. This makes the Forwarding (IP) virtual server the BIG-IP virtual-server type designed to provide router-like Layer 3 forwarding behavior.

BIG-IP processing is inherently stateful, so to approximate stateless router behavior, F5 uses specific FastL4 profile settings with the IP forwarding virtual server. FastL4 is supported with Forwarding (IP) virtual servers and provides efficient Layer 4 packet processing.

Option C is deceptive. BIG-IP does have a virtual server type called Stateless , but F5 documents that this type applies specifically to UDP traffic , requires a default pool, and has significant configuration restrictions. It is therefore not the general mechanism used to emulate stateless IP routing.

A Standard virtual server performs full-proxy processing, while Performance (Layer 4) is primarily used for high-performance Layer 4 application delivery and can use pools. Neither is the intended router-emulation configuration.
