Connecting to a remote AMX system via a WAN IP

Before you begin we highly recommend that you either lock down access to certain IP addresses or, if not practical, ensure that authentication and encryption is enabled for the AMX controller. This will help prevent outside parties from accessing the system.

STEP 1 Determine the WAN IP address

Independent of using a VPN connection, you will need to know the WAN IP address for the location you want to connect to. If the WAN IP is dynamically assigned by the ISP i.e. not a fixed|static IP, then you will need to utilise a Dynamic DNS service like A dynamic DNS service will allow you to always resolve the IP address of the location using your chosen domain-name eg

To determine what the WAN IP address of your location is, on a computer open a browser session and navigate to and it will list the current WAN IP for your network. If using Chrome, you can simply type “what is my ip?”

STEP 2 Is Port forwarding enabled to the AMX Control System?

You will need to ensure that port forwarding is enabled within the router configuration at the site. Specifically, Port 1319, which is the default port for AMX ICSP communications, will need to be forwarded to the IP Address of your target AMX Control System.
NOTE: You may want to turn on Security for the AMX Control System, and select ICSP and Encrypt ICSP. If you do so, all devices that connect to the AMX Control System via ICSP will need to have their connection profiles updated with the Username|Password that you define within the AMX Control System's Security - User Level: profile.

STEP 3 Test port forwarding

Then, from outside of the target network [in case your router does not provide reverse lookup], to determine if port forwarding is up and running correctly, open a command prompt session and type in: "telnet 1319" .

If port forwarding is configured correctly, you should see something similar to the following:

This has proven that you can establish a connection to your NetLinx master from outside of the target network.

At that point, all that is required to connect with the AMX Control System from TPControl is to enter the WAN IP or Host-Name in the TPControl Profiles Host field, and TPControl will establish a connection with the AMX Control System when connecting to any network.
