“Ethernet Port 1 (Online)” not accessible on Viewtron NVRs/DVRs

If you’re configuring a Viewtron NVR or Hybrid DVR for remote access or custom network settings and can’t select the correct Ethernet interface (Ethernet Port 1), there’s a simple setting that may be causing the issue:

First, go to the Network page.

Once in the Network menu, go to PPPoE.

Make sure that the check-box is Disabled, and then click Apply.

Now, go back to the TCP/IP page. Enabling and Disabling PPPoE may clear your TCP/IP network settings, so be sure to re-enable Obtain an IP Address Automatically. If you are using a custom network setup you can skip Step 3 on the chart and use your own custom settings.

What is PPPoE?

• PPPoE (Point-to-Point Protocol over Ethernet) is a method that allows a device to connect to an ISP using a username and password over an Ethernet connection.

• It is commonly used by DSL and some fiber providers that require authentication to access the internet.

• In most networks, the router handles PPPoE, so individual devices (like NVRs or DVRs) do not need it enabled.

If Enabled:

• The recorder locks certain manual network configuration options.

• The TCP/IP interface selection becomes restricted.

• “Ethernet Port 1” may be unavailable or greyed out in the TCP/IP menu.

Most installations do not require PPPoE because the router handles the internet authentication—not the recorder.
