Which two statements are true about persistent NAT? (Choose two.)
A.
The permit target-host-port statement allows an external host to initiate a session to an
internal host on any port, provided the internal host previously sent a packet to the external
host.
B.
The permit target-host statement allows an external host to initiate a session to an
internal host on any port, provided the internal host previously sent a packet to the external
host.
C.
Port overloading must be enabled for Interface-based persistent NAT.
D.
Port overloading must be disabled for Interface-based persistent NAT.
Note: Port overloading is used in Junos OS only for normal interface NAT traffic. Persistent NAT does not support port overloading, and you must explicitly disable port overloading with the port-overloading off option at the [edit security nat source] hierarchy level.
target-host—All requests from a specific internal IP address and port are mapped to the same reflexive transport address. An external host can send a packet to an internal host by sending the packet to the reflexive transport address. The internal host must have previously sent a packet to the external host’s IP address.
