Hello Need help on Nat exempt.

I'm looking to configure a nat exempt for couple of Hosts in X-DMZ to any interface. so, what would be the correct way in 9.1 version of ASA.

 

object-group network Sensors

  network-object host 10.14.X.X

 network-object host 10.14.X.X

1.  nat ( X-DMZ ,any) source static Sensors Sensors destination static any any description nat exempt

                                                              or

2. nat exempting for each of the interfaces

 nat (X-DMZ, Leveraged) source static Sensors Sensors destination static any any description nat exempt

nat (X-DMZ, Inside) source static Sensors Sensors destination static any any description nat exempt

nat (X-DMZ, Outside) source static Sensors Sensors destination static any any description nat exempt

nat (X-DMZ, VDMZ) source static Sensors Sensors destination static any any description nat exempt

nat (X-DMZ, AND) source static Sensors Sensors destination static any any description nat exempt

 

Below are the security levels applied.

Cisco Adaptive Security Appliance Software Version 9.1(3) context.

 

ASA# sh nameif

Inside                                        Inside                      100
TenGigabitEthernet1/1.X    Leveraged                      50
TenGigabitEthernet1/1.Y     AND                              50
TenGigabitEthernet1/3.Z     X-DMZ                           40

I think both are valid (starting  ASA 8.3 and newer)

You can find the sintax here:  http://www.cisco.com/c/en/us/td/docs/security/asa/asa91/configuration/firewall/asa_91_firewall_config/nat_objects.html
