Create Port Forward on Cisco ASA 9.9 using ASDM

Posted on by Jordansphere

In this example I will be opening port 3389 to a VM called RDP-Machine (192.168.2.200) There are two steps when creating a port forward:

 

1) NAT Policy

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


ASA-NAT1

 

Click Advanced

ASA-NAT2
 

2) Create Access Rule

Firewall -> Access Rules -> Add Access Rule

ASA-NAT3

Note: You may need to add RDP as service.

 

The following config was added to the config 

object network RDP-Machine
 host 192.168.2.200

access-list outside_access_in extended permit object RDP any any

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