In SmartView Tracker, you see an entry for an outbound connection showing address translation. But when setting SmartView Tracker to show all entries for that connection, only outbound entries show. What is the possible cause for this?

A.
The entry is for a Static NAT connection, from a specific host that has been infected by a worm.

B.
The entry is for a Hide NAT connection from a specific host.

C.
The entry is for an automatic Static NAT connection, where inbound traffic is managed by a separate rule.

D.
The entry is for a manual Hide NAT connection, from a specific host infected by a worm.
