Assume a client's traffic is being processed only by a NAT; no SNAT or virtual server processing takes place. Also assume that the NAT definition specifies a NAT address and an origin address while all other settings are left at their defaults. If the origin server were to initiate traffic via the BIG‐IP, what changes, if any, would take place when the BIG‐IP processes such packets.

The BIG‐IP would drop the request since the traffic did arrive destined to the NAT address.
The source address would not change, but the destination address would be changed to the NAT address.
The source address would be changed to the NAT address and destination address would be left unchanged.
The source address would not change, but the destination address would be changed to a self‐IP of the BIG‐IP.
