Create Port Forward on Cisco ASA 9.9 using ASDM

In this example I will be opening port 3389 to a VM called RDP-Machine ( There are two steps when creating a port forward:


1) NAT Policy

Go to: Firewall -> Objects -> Network Objects/Groups -> Add -> Network Object



Click Advanced


2) Create Access Rule

Firewall -> Access Rules -> Add Access Rule


Note: You may need to add RDP as service.


The following config was added to the config

object network RDP-Machine

access-list outside_access_in extended permit object RDP any any

object network RDP-Machine
 nat (any,outside) static interface service tcp 3389 3389
