I have CenturyLink gigabit over fiber. They require a PPPoE login along with the interface being set to VLAN 201. I cannot get this to work for anything.

I have changed my external interface to PPPoE and set the userid and password. I have setup a VLAN with 201 as the tag, set to the same interface as the PPPoE interface. The interface shows link, but never gets an IP address.

Is there any way to get this to work?? Is this a bug? My configuration screenshots are attached.

    It does not appear to be supported through the webconfig, but, looking at this old post, it looks very simple. Create your VLAN as you have. Create your PPPoE interface as you have, connected to the basic interface that you've VLAN'd. Then edit the file /etc/sysconfig/network-scripts/ifcfg-ppp0 to change the "ETH" line to point to the VLAN interface enp1s0.201. You may not be able to edit the PPPoE interface any more as it could overwrite your change.

    The network start command is now:
    systemctl restart network.service
    but you may be able to get away with:
    ifdown ppp0 && ifup ppp0
