After updating to CenturyLink Fiber, I went down the rabbit hole trying to figure out how to get my own dd-wrt router directly connected to their ONT. This required tagging the WAN traffic with vlan id 201, and performing PPPoE to authenticate.
After not being able to figure it out from the web UI or help pages, I went to the forum and read a multitude of posts. Most of the posts were quite old and had large listings of commands to run. Thinking there must be a better way, I persevered to figure out the simplest method and share in case it's helpful:
1) Setup->Networking->VLAN Tagging, Add a VLAN interface for the WAN port with Tag Number 201. On my router 'eth0' is the WAN port and applying this configuration creates an 'eth0.201' port.
2) Setup->Networking->Port Setup, Select 'eth0.201' for the WAN Port Assignment. You may need to refresh the page until the 'eth0.201' port shows up.
I thought I'd be all set at this point. It took a lot of digging to find the last step:
3)
Code:
nvram set pppoe_wan_ifname=eth0.201
This must be run on the console (I did so via SSH login), as I found no UI setting for this.

There is an easy way:
swconfig dev switch0 set enable_vlan 1
swconfig dev switch0 vlan 2 set vid 201
swconfig dev switch0 vlan 2 set ports "0t 5"
swconfig dev switch0 set apply
Put it in the startup script. Keep WAN on default VLAN2
Your WAN vlan is 2, and that is what is throwing me by the pictures in your OP.
The VLAN is exactly as is shown in screen shot. Either the UI is displaying the wrong value or you are mistaken, but that is a screen shot after doing the steps I described on a dd-wrt after a fresh reset.

The WAN will still be on eth0. There will not be any eth0.201 interface.

I just wanted to say THANK YOU to Channel11.5. I too started down the rabbit hole and luckily during my search I found your thread. These instructions worked for me perfectly. CenturyLink 1 gig service, R7800, and DD-WRT v3.0-r42054 std (01/21/20) firmware.

Hi Channel11.5,
thank you for your post. I found it searching for a solution to a similiar setup from my fiber provider (vlan-id 13 for me). I tried following your instructions, but it did not work. However, i then took a deep look at the Switched Ports Article, especially the "802.1q VLAN trunking" example and implemented the following (beeing on a device with cpu port 5 and wan port 0, the article helps you figure that out):
Code:
nvram set vlan13ports="0t 5"
nvram set vlan13hwname="et0"
The port0vlans variable i augmented with "13 16" (13 for vlan-id 13 and 16 to enable tagging)
The port5vlans variable i augmented with "13" for the vlan-id 13 it is part of now, so that the cpu sees the vlan.
I left the wan interface unchanged (i think it was vlan2) but added
Code:
nvram set pppoe_wan_ifname=vlan13
Now, after setting the vlan13 up on the WAN port with the steps above and explicitly setting the pppoe-wan-device to vlan13 from the cmdline, the pppoe configuration in the gui did work.
Hope this helps someone.
Best regards,
dmk

This is an old thread and no longer valid.
With the current firmware you only need to create a VLAN tag for eth0 in the tab "Networking" and use the VLAN as WAN port (WAN port assignment).

Hey bud, I am trying to set this up like you said for vlan id 35 for WAN.
I first go to switch tab and leave everything the way it is and just click check mark on tagged for WAN. it's under vlan 2 at this time.
Then go to networking tab, I add etho with tag 35 for tagging.
After that I got to WAN port assignment set that to eth0.35
I am unsure what I am doing wrong anymore. Tried different firmware and nothing.[/img]
Sorry the thread is about the R7800 (Atheros)and PPPoE
Your DIR890l is a completely different router and Broadcom based (so wrong forum) and the DIR probably also has a different switch configuration than the R7800
Some routers have a VLAN based configuration out of the box (unlike the R7800)
(don't know, I don't know the router)
Anyway if you tag VLAN 2 on the switch then the switch also has a tagged VLAN2
I didn't write anything about the tab "switch config"... you shouldn't use it on the R7800 - "switch config" is not really functional on the R7800 and if you pressed 1x Save in the tab you can only restore the default configuration by a reset.
I would recommend you to ask your question again in the Broadcom forum.
however there are basically 3 ways to assign a custom VLAN tag to the WAN port.
1. networking tab
2. switch config tab (if the tab on the router is working correctly)
3. swconfig command line
So 1 or 2 or 3 but no mix of the different variants (I think this is the first problem you have)

Hello.
Im about to install dd-wrt on my netgear r9000.
My ISP works with PPPoE and VLAN20.
Could i follow your words? Will they work on my router?
I have read a lot of threads about it but all of them are very old so im too confused.
