I have an optical fiber connection to internet using PPPoE. I have connected my Linksys WRT 1200 AC (running DD-WRT firmware) instead of the router provided by the ISP to the ISP's ONT box. I first tried the setting Automatic Configuration - DHCP but could not get Internet. Then I set the connection type to PPPoE with the user name and password supplied by the ISP, but got no Internet again. What am I missing or doing wrong? Will appreciate any advice. ISP refuses to help regarding a router not supplied by them.

Does the router get an ip address on the WAN port?

Is VLAN used on the network? You have to ask your ISP for the correct VLAN number (pvid).

Hi Per Yngve. No, the router (my DD-WRT router) does not get the IP address on the WAN port (it is 0.0.0.0). ISP's router does.
ISP support has no clue about VLAN, but from the scarce info presented on the ISP's router interface I can read the following:

Vlan8021p: 1
VlanMuxId: 6

[Per Yngve Berg]

You have to set the WAN Port to tagged VLAN6.
This post sets it to 621.

[Ivo_K]

I ran the suggested commands. Unfortunately didn't help. Situation is still the same.

[Per Yngve Berg]

Did you reålace 621 with 6?

[Ivo_K]

Tusen takk Per Yngve for your kind help. Yes, I did the replacement. The commands I ran are:

swconfig dev switch0 set reset 1
swconfig dev switch0 set enable_vlan 1
swconfig dev switch0 vlan 1 set ports "5t 0 1 2 3"
swconfig dev switch0 vlan 2 set ports "5t 4t"
swconfig dev switch0 vlan 2 set vid 6
swconfig dev switch0 set apply
ifconfig eth0 up
ifconfig eth1 up
vconfig set_name_type VLAN_PLUS_VID_NO_PAD
vconfig add eth0 1
vconfig add eth0 2
nvram set pppoe_wan_ifname=eth0.6


...and unfortunately I still cannot connect.

What ROUTER? What Version of DD-WRT??????

[Ivo_K]

Linksys WRT 1200 AC
Firmware: DD-WRT v3.0-r34311 std (12/29/17)

Following the trail of Per Yngve's advice, I searched for a way to set the VLAN port to a tagged one. It didn't work with the suggested script but there is a possibility through DD-WRT interface. On SETUP/NETWORKING the very first option is VLAN TAGGING. I set the eth0 port (that's the VLAN port) to tag 6, priority 0. Then further down on the same page, under PORT SETUP/WAN Port Assignment I selected the newly created eth0.6. Now everything works perfectly.

Many thanks again, Per Yngve for giving me the right clues!

I have the exact same issue.
How did you manage to solve this problem?
Thanks!

Hello,

I have LinkSys EA9600 DD-WRT v3.0-r44483 (10/02/20) and trying to achieve the same goal but with VLAN 35.

So I did SETUP-NETWORKING
ADD - VLAN 0 eth0 35 0
and
Port Setup - WAN Port Assignment eth0.35 (was vlan2)
but not working.

Since my Bridding table is:
br0 - no - eth1 eth2 vlan1 vlan2
and
Port Setup - WAN was vlan2
should I be setting my VLAN 0 to vlan2 instead of eth0?

Thank you.
