Telo preventing PPPoE when connected

Post by abqbill » Sun Aug 02, 2020 7:56 am

My configuration:

Code: Select all

[ Internet ]
      |
      |                         +--------+
    +-----------+               |  WiFi  |
    | DSL Modem |               | Router |
    +-----------+               |        |
      |                         |  W  L  |
      |                         +--------+
    +---------+                    |  |
    | Switch  |                    |  |
    +---------+                 +--------+
      |  |  |                   | Switch |
      |  |  +-------+           +--------+
      |  |          |               |
      |  |          |               |
   +--------+   +----------+    +----------+
   |  H  I  |   | Homeplug |====| Homeplug |
   |        |   +----------+    +----------+
   |  Telo  |
   +--------+

   H = HOME port                W = WAN port
   I = INTERNET port            L = LAN port
The switches provide the connectivity from the WiFi router to the internet, and provide LAN-side connectivity to the DSL modem (view status page, etc.).

The WiFi router uses PPPoE to connect to the internet. This all works as expected.

DSL modem is in "transparent bridge" mode. DHCP server is disabled on the Telo.

The odd thing is that when I reboot the WiFi router, the Telo is answering the PPPoE request from the WiFi router. To get things working again, I have to do these steps:
  1. Unplug Telo
  2. Log onto WiFi router and disconnect internet connection
  3. On WiFi router, connect internet again (now ISP responds to PPPoE instead of Telo)
  4. Power Telo back on
After this, everything is working again.

The crux of the problem is that the Telo responds to the PPPoE and breaks my Internet connection until I unplug it. Once the Telo is unplugged, my ISP responds to the PPPoE connection and my connection is back up.

Is there any way to prevent the Telo from responding to the PPPoE request from my WiFi router?

The configuration should be DSL Modem to WiFi router W.
WiFi router L to a switch.
Switch to Telo I
Telo H should not be connected to anything.
Telo should be in DHCP mode in case you need to connect a computer to H to configure it.

Never connect both ports of a Telo to the same subnet.

Resolved: I had configured a DHCP reservation for the MAC address of the HOME port instead of the INTERNET port.

Corrected the DHCP reservation and disconnected the HOME port cable from the switch.

Now the behavior is correct: INTERNET port gets reserved IP on my LAN, and I can administer using that IP. In this scenario the HOME port is not used.
