Hi,

I'm having trouble configuring my R6700v3 to talk to my CenturyLink endpoint via PPPoE. The issue seems to be vlan configuration, and I'm unsure exactly how to actually set the outgoing tag, which needs to be 201.

I've tried various things, for example

Code:

root@DD-WRT:~# swconfig dev eth0 port 5 set pvid 201
root@DD-WRT:~# swconfig dev eth0 set apply


but that seems to get reset when I press "connect".

I've added a tag via

Code:

root@DD-WRT:~# nvram set vlan2ports="0 5 201t"
root@DD-WRT:~# commit


and that doesn't seem to work.

I've tried creating a vlan tag in the gui, and setting the WAN device to
Code:
vlan2.201
, though it does show up in /tmp/ppp/options*, so it seems to take, but not actually work.

I've tried explicitly setting
Code:
nvram set pppoe_wan_ifname=vlan2.201
, but still no luck.

Any ideas on how I would actually configure the WLAN vlan tag?

Thanks.

What build are you running?

Things have changed considerably on recent builds

Sorry, should have included that in the first post. I've tried all of this on 49626 from August 03, which I got from: https://ftp.dd-wrt.com/dd-wrtv2/downloads/betas/2022/08-03-2022-r49626/netgear-r6700v3/

Thanks.

I spent some more time messing around with this. I created a device by hand without all the UI bits just to test, and it was definitely using vlan id 201:

Code:

root@DD-WRT:/# cat /proc/net/vlan/eth0.201
eth0.201  VID: 201   REORDER_HDR: 1  dev->priv_flags: 1
         total frames received            0
          total bytes received            0
      Broadcast/Multicast Rcvd            0

      total frames transmitted          298
       total bytes transmitted         9536
Device: eth0
INGRESS priority mappings: 0:0  1:0  2:0  3:0  4:0  5:0  6:0 7:0
 EGRESS priority mappings:


I used the manual nvram setting
Code:
nvram set pppoe_wan_ifname=eth0.201
to get it to use this interface:

Code:

root@DD-WRT:/# cat /tmp/ppp/options.pppoe
plugin /usr/lib/rp-pppoe.so

nic-eth0.201
noccp
nomppc
noipdefault
noauth
defaultroute
noaccomp
nobsdcomp
nodeflate
nopcomp
nomppe
usepeerdns
user '[redacted]@centurylink.net'
password '[redacted]'
default-asyncmap
mtu 1492
mru 1492
persist
lcp-echo-interval 3
lcp-echo-failure 20
lcp-echo-adaptive


I tried with various versions of my username as well (with the @centurylink.net, @centurylink.com, without both), and no luck.

All I end up with in the syslog is:

Code:
Jan  1 00:53:32 DD-WRT daemon.notice pppd[32133]: pppd 2.4.8 started by root, uid 0
Jan  1 00:53:48 DD-WRT user.info : [sfe] : shortcut forwarding engine successfully stopped
Jan  1 00:53:48 DD-WRT user.info : [sfe] : shortcut forwarding engine successfully started
Jan  1 00:53:49 DD-WRT user.info : [sfe] : shortcut forwarding engine successfully started
Jan  1 00:53:49 DD-WRT user.info : [pppd] : daemon successfully stopped
Jan  1 00:53:49 DD-WRT daemon.info pppd[32133]: Exit.


I looked at the pppd man page, and it doesn't have anything about the nic setting, so maybe that's wrong? Anyway, I don't know anything about pppd, but it seems like it is probably misconfigured.
