[Hints] VDSL2 / Speedport Smart 2 / OPNsense 18.1.6

[Tecuma]

Hi community,

it cost me some time to get my setup running. I would like to give some information how to do that so if someone has the same components / setup he might save some time.

My setup:
- Telekom VDSL2 100Mbit
- Telekom Speedport Smart 2 (SS2) as Modem
- PC Engines APU2C4 with OPNsense 18.1.6

The Speedport Smart 2 comes by default with the IP 192.168.2.1.
If the DSL connection is not working you have to check the status again before able to continue with the setup wizard.
After the setup wizard you can see the web gui. Either in "Heimnetzwerk" (Home Network) or "Einstellungen" (Setup) you are able to declare this device to act as a modem.
The device will reboot after this configuration. It will change its IP to 169.254.2.1 (ports 1-3).
When you connect again you will see only a status page.

The WAN port from the APU2C4 has to be connected to LAN port 4 of the SS2.
In OPNsense you have to configure
- PPPoE user (anschlusskennung+zugangsnummer+mitbenutzer@t-online.de)
  Example: 1122334455669988776655440001@t-online.de
- PPPoE Password (Ihr persönliches Kennwort)

Telekom use VLAN id 7. In OPNsense you have to configure this VLAN id in Interfaces -> Other Types -> VLAN.

Additionally you have to assign this new PPPoE Interface with VLAN 7 to the WAN port. Interfaces -> Assignments. This step took me some time and was the reason to create this topic in the forum.

After this my setup was running properly and I could enjoy 100Mbit
