Configure RDP with DNAT

I had this issue when I installed our UTM, it seems that the UTM did not like the normal rules, so i had to call support to work this one out, hope it helps.

Hi Jason,

Thank you for your reply and help. But it seems I have also changed the "Source" to External Address and "Destination" to Internal Address still cannot get through.

And I did created the "Additional Address" within the "Interface" module in order to suite with the print screen that you have provided.

Any ideas?

Thanks.

Hey Clyde.

It seems correct on the UTM side. I would change "Going to" to the external interface address as per rule #4 in Rulz. Other than that, check your server firewall and gateway to make sure it can actually respond NATed traffic back to the UTM. Use the same link above for tips on how to diagnose the issues you are having.

From outside, what IP are you hitting, CAM EXT IP or your WAN Address.
Use the logic and everything should work

Hi Giovani,

Thank you for the reply and the explanation provided.

Yes, you are right. What I did is to change the "Going to " to the external interface address and the source to the intended host IP address then everything is worked now!

Thanks again!

Cheers.

Hi Oldeda,

Thank yo for the clarification and it seems it is working now!

Cheers.

Hi Clyde and welcome to the UTM Community!

Since DNATs on the External Interface only work for traffic coming from outside your LANs, it's clearer to use "Internet IPv4" in the source instead of the "Any IPv4" object.  To understand this better, consider Accessing Internal or DMZ Webserver from Internal Network.
