This guide will show you how to connect the bero*fix card with the LAN and WAN.

Connecting the beroNet bero*fix card

  1. Insert the Beronet Berofix into the PC. After the system has booted you will have a new network device available.
  2. Windows usually detects the card as a “Realtek RTL8139”. If you have any other Realtek cards installed in your system, you can identify your new card based on the MAC address starting with: 00-50-C2-XX-XX-XX.
  3. Name the network card Beronet.
  4. Assign the static IP address 10.0.01/16 to the network card “Berofix”.
  5. Open the Web browser to and login (default login: admin/admin).

  1. Go to Preferences + > Network settings” and change the IP Address to a free IP in your network.  For this example we will continue to use

  1. Save the configuration and activate the settings (card will reboot).
  2. In the Windows Network Card settings select the network card which is already connected to your network and the Beronet card, and bridge them together. To do this, right click on the Network card and select “bridge network connections”.

NOTE: The “Network Bridge” removes all IP addresses from your network adapters and assigns a new IP address via DHCP. This means that previous IP settings are lost. So now you re- assign the original IP address you had before on your LAN adapter to your bridge adapter.

You can now access the Beronet Bero*fix management web interface via the IP Address you specified in Step 6.

Additional Settings

In newer versions of Windows, Windows intend to randomize the MAC address of the bridge adapter between the two MAC addresses of the real network interfaces. This will cause an issue with the license activation of your 3CX. The solution is to spoof the same MAC for both network adapters and set them in the registry. The below steps are best known practice:

  1. Use CMD and run IPconfig to get current MAC address of bridge adapter.

  1. Open Network settings of the “beronet network card” → advanced tab → Network Address

  1. Open the registry and browse to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002BE10318}
  2. Change the NetworkAddress field to the same MAC as seen in the ipconfig and set in the beronet card.

  1. Reboot the host several times to ensure that the MAC address of the bridge adapter remains the same.
