Configuring NAT Settings

As a Managed Service Provider, you would need to manage your client desktops from your network. The RMM Central agents residing in the computers of your clients need to reach the RMM Central Server installed in your network via internet. This means that the RMM Central Server is reachable via Public IP Address.

Installing RMM Central as an Edge device often involves hardening the OS against security threats/attacks with appropriate firewall configurations. It is simpler to have the RMM Central Server installed in your private network and configure your external router to forward the requests to your private IP Address rather than moving RMM Central to the Edge.

The NAT settings lets you to specify the public IP Address and ports to which the requests/data from the RMM Central Agents will be sent. The requests gets translated at your router to reach the RMM Central Server.

To configure the NAT Settings, follow the steps below:

  1. Select Admin --> NAT Settings
  2. Specify the Public IP Address, Server Port, Remote Control and File Transfer Ports and click Save.


  1. This step is not required, if the computer where RMM Central Server is installed is directly accessible via internet.
  2. The default port numbers are 8041, 8047, and 8053 for Server, Remote Control and File Transfer Ports respectively.

Modify your NAT Settings

NAT Settings once configured can be modified by navigating to the same page. When the NAT Settings is modified, previously managed devices will try to contact the pervious FQDN/IP address, however the devices added to RMM Central's scope after the modification in NAT Settings will contact the updated FQDN/IP address.

To eliminate the communication break for the previously managed devices, the former FQDN/IP address should be mapped to the newly added one.

Secure Management of Over the Internet Devices

Secure Gateway Server is used to secure the communication between the RMM Server and managed or monitored devices over the internet. This is an additional layer of security for the management of devices. To configure Secure Gateway Server, the public FQDN/IP address of the Central Server is mapped to the Secure Gateway Server.
