PPPoE on VLAN - impossible in UTM?

Hi Lock,

I see that you have two VLAN on eth0. Can you configure eth0 exclusively for the VDSL line. I think that should resolve your issue. I see that we do not have a KBA for VDSL configuration but check this external KBA here.

Hope that helps :)

As I mentioned, I need to have three VLANs on eth0 (I only have one NIC), and one of them needs to be DSL PPPoE. 

And I cannot go any further into configuration you linked to, because I cannot save the interface state.

Judging from this thread it was possible: https://community.sophos.com/products/unified-threat-management/f/hardware-installation-up2date-licensing/29112/pppoe-over-vlan but apparently it no longer is (vide: my screenshot from the first ). It appears to be either a regression/bug or purposeful removal of feature.

This is very unfortunate and I would be happy if there was a way around it, like setting up VLANs from command line.

Hi Lock,

If you check the help doc for UTM; in the interface> Ethernet section it states: For an external connection (e.g., to the Internet) choose the network card with SysID eth1. Please note that one network card cannot be used as both an Ethernet interface and a PPP over Ethernet (PPPoE DSL) or PPTP over Ethernet (PPPoA DSL) connection simultaneously.

Hence, not possible.

I see. Thanks.
I don't understand why this limitation has been introduced. Doesn't make sense to me.
In pfSense there is no problem of using the same physical interface to multiple VLANs, including PPPoE DLS connections.
