The Vigor 130 modem is capable of passing through VLAN tags provided by the connected router.

In this scenario, the connected router establishes the Internet connection over its Ethernet WAN port, adding the VLAN tag on its Ethernet port.

The Vigor 130 modem will operate purely as a VDSL to Ethernet bridge, without adding a VLAN tag to the VDSL traffic.

Vigor 130 Modem Setup

Access the Vigor 130’s web interface and go to [Internet Access] > [General Setup].

On that page, set the Service and Customer VLAN tags for VDSL2 to Disable, then click OK, which will prompt to restart. Ignore that for now and continue to the next step.

Configure VLAN tag settings on Vigor 130. Disable customer & service VLAN tags

Now go to [Internet Access] > [MPoA / Static or Dynamic IP] and enable the MPoA (RFC1483/2684) interface.

Click OK to save and apply the change. This will prompt the modem to restart, click OK to proceed with the restart.
Upon restarting, the modem will no longer provide an IP address through DHCP, which is required by the MPoA Bridge Mode configuration, for full bridging to take place.

With the Vigor 130 modem now configured to bridge VDSL to Ethernet with no VLAN tag added by the modem, the router can be configured to use this.

Check the DSL LED on the Vigor 130 modem. While it’s flashing, the DSL modem has either not detected (blinking slowly), or is syncing with the line (blinking rapidly).
When the DSL LED is lit solidly, the Vigor 130 has established the link to the DSL line and can be used for bridging.

Connect the Vigor 130’s LAN port to the Ethernet WAN port on the router.

Vigor Router Setup

On the router, go to [WAN] > [General Setup] and select the WAN interface that the Vigor 130 modem is connected to. In this example, WAN2 is used on a Vigor 2866 router:

v130 vlanonrouter 3

In the settings for the Ethernet WAN port with the modem connected:

  • Set VLAN Tag insertion – Customer to Enable
  • Specify the correct Tag value for your ISP:
    • With most UK ISPs that would be 101
    • In Ireland that would typically be 10

Click OK to save and apply that setting. The router will request to restart to apply the change, ignore that for now and proceed to the next step.

Go to [WAN] > [Internet Access], select the correct Access Mode for your ISP, in this example PPPoE

is selected as the Access Mode for WAN2 on the Vigor 2866 router. Click Details Page to proceed.

On the WAN – Details Page, this will open the settings for the selected Access Mode.

  • Enable the Access Mode i.e. enable PPPoE
  • In the ISP Access Setup:
    • Leave the Service Name field blank
    • Enter the Username & Password supplied by your ISP
  • In the IP Address Assignment Method (IPCP) – Fixed IP setting:
    • If your ISP provides a public static IP address, set Fixed IP to Yes, then enter the Fixed IP Address in the textbox below
    • Otherwise, leave the Fixed IP set to No (Dynamic IP)

v130 vlanonrouter 5

Click OK to save and apply the change. The router will ask to restart, click OK again to proceed with the restart.

Once the router has restarted, check the WAN status on the [Dashboard]:

v130 vlanonrouter 6

In this example, the WAN2 interface has successfully connected to the Internet, which indicates that the VLAN tag on the Ethernet WAN port is being passed through correctly.

The connection can now be used for Internet access.
