PPPoE Config for D-Link DIR-3060

Installing and Using OpenWrt
1

Using a newly acquired D-Link DIR-3060 to connect to Internode.on.net NBN FTC modem via PPPoE, and having no luck.

The router: https://openwrt.org/toh/d-link/dir-3060_a1

PPoE configuration parameters from old router:
VLAN ID: Enable
VLAN ID (1-4094): 2
Internet Connection Type: PPPoE
Username: redacted@internode.on.net
Password: redacted
Confirm Password:
Connection Mode: Auto
Authentication Type: Auto
IPv4: Enable
IPv6: Disable
Service Name:
Access Concentrator Name:
MTU Size: 1480
NAT: Enable
Full-cone NAT: Disable
IGMP Proxy: Enable
Use the IP Specified by ISP: Disable
Echo Request Interval: 30
Use the Following DNS Addresses: Disable
Do NOT Clone MAC Address

What I tried in /etc/config/network:
config interface 'wan'
option device 'eth0.2'
option proto 'pppoe'
option username 'redacted@internode.on.net'
option password 'redacted'
option mtu '1500'
option pppd_options 'debug'
option ipv6 'auto'

In LuCI, this sets my wan device to 'Software VLAN eth0.2 (wan)'.

Despite all efforts, I can't seem to get past the 'No default route present' error.

Completely exhausted. Anyone care to please take a stab?

Ignore this update: I've abandoned PPPoE on the wan, started with a fresh config, and attached to my normal router's wifi. Now it works.

I had a conflict between the IP address of my openwrt router on it's lan, and the IP address for the gateway supplied by my usual router's DHCP wifi server.

Some ISPs restrict the connection to one single route. Try to clone the MAC address from the other router.

Thanks, eduperez.

Didn't know some ISPs did this, but I've used other routers with the modem my ISP provided. Thankfully, we can eliminate mac filtering. Good clue.

Your router is trying to reach the PPPoE server (PADI packets), but it is not receiving any answer (PADO packets). Either it is not connected properly to the modem, the VLAN is not configured properly (it looks correct to me), the interface is wrong (it looks correct to me, too), the modem is just refusing to answer, ...

This seems not to rhyme, but you do not need to force an MTU in /etc/config/network, so maybe remove that line? Now, MTU issues might not be the reason for the PPPoE negotiation to go nowhere (as configuration packets likely are not fullMTU size anyway).

For debugging, please post the output of ifconfig.

Thanks, moeller0.

Oops, I posted an error. I think it was LuCI that complained about the mis-configured MTU size, and I did actually correct it to 1500 before giving in. Good pick-up, though my problem runs deeper.

Okay, nothing heard back from my router, after PADI packets sent. I'll have to post my ifconfig output. Gimme a tick...

Yes, but that really only tells us that either the PADI did not reach the remote side, or the response PADO from the remote side did not reach your router. There are, unfortunately, quite a lot of reasons for that to happen, starting from a not connected cable, over VLAN issues or more subtle problems.

Okay, Back to trying to setup a PPPoE connection to my service provider via NBN FTC modem.

Seems I can get an ipv6 connection with VLAN 2 tagging, but the modem only does ipv4. I can't seem to figure out the PPPoE setup that will give me an ipv4 link. I think that's what the situation is?

Anyone able to please shed some light on what might be going on?

TIA,

What router model was that, and was that connected to the same modem you are trying to use under OpenWrt?

11

Thanks, moeller0.

Same modem connected to each router, and the old router is a TP-Link Archer VR1600v.

HTH,
M.
