Remote Access


The UCX remote access feature allows support of UCX systems remotely, without requiring opening ports on the customer premises firewall. Access is provided by a centralized OpenVPN server, secured by client certificates on the UCX system as well as the connecting PC. Once you have configured Remote Access on your UCX system, you can leverage the VPN connection to access additional devices that are connected via the same internal LAN environment, such as DSM16 modules or cards.

To use the remote access package, you need to have OpenVPN installed on your PC or Mac computer. Additionally, you need to register the UCX system for remote access.

Please contact E-MetroTel support ([email protected]) to request a user or partner account to access the feature.

To allow the VPN connection to be established, the UCX system must be able to communicate with our server ( using the TCP port 1194.
The remote access server assigns virtual IP addresses ranging from to ( to remote systems. To avoid IP address conflicts, do not use IP addresses in the same range for your UCX system.

User Accounts

User accounts are for your companies' UCX installers and support personnel. They can use these accounts to create PC and Mac certificates, register UCX systems, and login to the remote VPN network. 
A user account cannot be used to manage or delete certificates created by another account and/or to de-register or re-register UCX systems registered by another account.  Please contact your E-MetroTel partner account holder if you need further access.

Partner Accounts

Partner accounts are assigned to one or more individuals in an E-MetroTel partner company. As with user accounts, partner accounts can create and manage their own PC, Mac, and UCX certificates, and log onto the remote network.
Additionally, partner accounts can be used to manage certificates created by another partner or user account in their own company.


  • You have a Remote Access user or partner account provided by E-MetroTel.

Add New Remote Host

The Remote Access functionality allows you to connect securely to other devices within the same LAN environment as the UCX system. For example, if you have DSM16 modules or cards connected to the UCX, you can add their IP address as a new remote host, and the UCX will allow you to connect to that device using specific port numbers.


For example, if the IP Address of the DSM16 is, you would configure the remote host to support port 443 (for web access) and port 22 (for ssh access) as follows:

  1. Click on New Remote Host.
  2. Enter the IP Address of the device (, the Port(s) that you will want to use for connections (typically 443 and 22), and a Description (i.e. DSM16 #1). Then click Create.
  3. It will now appear in a list along with any additional Remote Hosts you create.
  4. Click Cancel to see the list this entry as well as any other Remote Hosts you have created.

Using the Remote Host to Connect to another Device

  1. In the Remote Host list, click on Connect in the row corresponding to the device you need to access.
  2. Click on the numbered link next to the port number you wish to use to connect. For example, to connect to the Web-based Configuration Manager for the DSM16 #1, press 8001.
  3. A new tab will appear in your browser, showing the IP address of the UCX and the port number used to connect to the device.
