Hello Cisco Community,
Guys, I need your support and comment about how stablish one Static Nat range port on the ASA 5520 IOS 8.2.
Example:
Private IP 10.1.1.1 ports 4000 - 4500
Public IP 200.100.10.1 ports 4000 - 4500
Regards and thanks!

Hi Lucio,
You can create a static NAT in 8.2 and permit only the set of ports using the access list to allow it.
For example
static (inside,outside) <public IP> <Private IP> netmask 255.255.255.255
Now create access list for thsi traffic.
access-list outside_in extended permit tcp any host <public IP> range 4000 5000
access-group outside_in in interface outside
Or you can upgrade the device to version above 8.3.

Hi Lucio,
We can not create static NAT for range of ports in 8.2 version, Need to write multiple Statements or perform a Static one-to-one NAT.. This can be done in versions above 8.3 where there is change in the configuration of the NAT.
Please refer "Static NAT for a Range of Ports" section

Hello Shivapramod M,
Thank you for your prompt response, so my only option is an upgrade to version IOS 8.3(4) or write line for line. Thanks again for your support and resolve my questions.
