Configuring Twice NAT
(Continued)
•
Destination addresses (Optional):
–
Mapped—Specify a network object or group, or for static
interface NAT with port translation only, specify the
interface
keyword. If you specify
ipv6
, then the IPv6
address of the interface is used. If you specify
interface
,
be sure to also configure the
service
keyword. For this
option, you must configure a specific interface for the
real_ifc
. See the
“Static Interface NAT with Port
Translation” section on page 1-5
for more information.
–
Real—Specify a network object or group. For identity
NAT, simply use the same object or group for both the
real and mapped addresses.
•
Destination port—(Optional) Specify the
service
keyword
along with the mapped and real service objects. For identity
port translation, simply use the same service object for both
the real and mapped ports.
•
DNS—(Optional; for a source-only rule) The
dns
keyword
translates DNS replies. Be sure DNS inspection is enabled (it
is enabled by default). You cannot configure the
dns
keyword
if you configure a
destination
address. See the
for more information.
•
Unidirectional—(Optional) Specify
unidirectional
so the
destination addresses cannot initiate traffic to the source
addresses.
•
Inactive—(Optional) To make this rule inactive without
having to remove the command, use the
inactive
keyword. To
reactivate it, reenter the whole command without the
inactive
keyword.
•
Description—Optional) Provide a description up to 200
characters using the
description
keyword.
