Can't get PPPoE working

[marmrk]

Hi all,

I have to connect to my ISP over ADSL + PPPoE and I have Speedtouch 780wl router in Router mode so each computer has to establish a PPPoE connection by itself.

I'm now struggling to configure PPPoE on RPI but without success.

I've managed to install ppp, pppoe and pppoeconf packages from debian repository and I created configuration for my account. But it seams that pppoe connection cannot be established.

This is pppd log:

I'm using Debian image from RPi download pages. I'm stuck here, so any help is appreciated.

You may be the first person to try setting up PPPoE on the R-Pi, at least I haven't seen anything on it before. I'm not a networking expert, but is there a reason you can't have the router do the PPPoE connection on the ADSL side by itself, and then appear as a normal DHCP server to your LAN?

[marmrk]

I really thought that setting PPPoE on RPi will be trivial. I can't establish PPPoE connection on router since it's locked in router mode which does not allow setting PPPoE connection. I could switch to bridge mode, but I don't have router admin password

I've had similar experiences with Linux in the distant past. My solution was to use a very handy 'free' commercial offering from Roaring Penguin. You can find it at http://www.roaringpenguin.com/products/pppoe It worked well for me!

Thanks, I will try it.

I'm already using this pppoeconf, pppoe and ppp on my laptop with Ubuntu installed and I did not have any problems.

Is PPPoE support enabled and compiled into the kernel or pppoe module loaded?

[marmrk]

I'm not sure, I've just used the Debian distribution published on Raspberrypi web site. Can you tell me how to check this?

[Floyd]

I don't have a Raspberry Pi yet so I just can guess.

Do a 'lsmod' first to check if the pppoe module is loaded. Then try to load the module with 'modprobe pppoe'. If the module isn't available you would get something like 'Module pppoe not found'.
If there is a file '/proc/config.gz' or '/boot/config-*' you could check if the symbol 'CONFIG_PPPOE' is set to 'y' (compiled into the kernel) or 'm' (loadable module).

I just downloaded the Debian image and it looks like there's no pppoe enabled in the kernel. Seems that you have to compile your own.

You can set the MTU of /dev/eth0 by using the ifconfig command.

I've installed pppoe conf from Roaring Penguin and it seems that pppoe connection is now established:

Thanks, this removes the error message but the connectivity problem still resides.

Yes, I will try to compile kernel with CONFIG_PPPOE and CONFIG_PPP_FILTER options set. I hope it will help.

I compiled kernel with PPPOE module and PPP filter enabled. I successfully loaded the module with modprobe pppoe.

But still I don't have success with configuring connection.

This is ifconfig pppoe output:

I wanted to report that I managed to establish internet connection with PPPoE.

After the kernel with appropriate PPPoE modules was installed, I reinstalled the pppoeconf and deleted previous configuration from /etc/ppp/peers/ directory. Then I followed the setup instructions from http://wiki.debian.org/PPPoE and I can report that it worked!

Hi, i have BT ADSL internet connection with AccessRunner PCI board on my PC. Will BT ADSL work with RaspPi?

Thanks

Hello mamrk!
I was wondering about the gape to connect RPi to ADSL. May be I understand Eben and the team: first task "learn programming the RPi" !
But seems You managed a bridge?
Could You please give a detailed list step by step of the procedure?
Yes, it is in the thread, ok!
But I think it would be a great help for the undeserving poor as Shaw lets Doolittle explain against Higgins and Pickering.
Now please excuse detour!
Greetings from Hamburg!

I tried everything. The rasberian kernel is missing a key piece here, preventing 3G connectivity.

[cyanarnofsky]

I am having similar issue. Wvdial and PPPoE. I dial up my 3G modem, connects fine. PPP grabs correct static IP from ISP. I can even ping the device and ssh into it through the modem but once inside the Raspi I can't ping anything external. :/

The key here is to purge /etc/ppp/peers/

I can't establish PPPoE connection on router since it's locked in router mode which does not allow setting PPPoE connection. I could switch to bridge mode, but I don't have router admin password :(

It is in fact the other way round. When ADSL adapter is in router mode then it can establish the connection by itself and after establishing the connection it can run DHCP. But when the ADSL adapter is in bridge (modem) mode, then you have to establish the connection by PPPoE (e.g. dial-up on Windows). So, your ADSL adapter is not in router mode but rather in bridge mode.

While you probably could ask your ISP to switch your ADSL adapter from bridge to router mode, there are many advantages of bridge mode over router mode so I would'n want to ask for that change. In fact, I called my ISP to upload the firmware into my ADSL adapter to switch it from router mode to bridge mode (my PC it is always on anyway so other devices can always access internet).

You said: '...so each computer has to establish a PPPoE connection by itself.' It doesn't have to. For example, I have one computer which establishes the connection and there is Internet Connection Sharing enabled on this computer so all other computers can access internet in the same way as if ADSL adapter would be in router mode. The only thing I have to set up for other computers is gateway and DNS server, which is an IP address of the computer which establishes the connection.

In case your computer is not always on you can simply plug in another ADSL adapter in router mode into your ADSL adapter which is in bridge mode - then this second router will be establishing the connection when your computer is turned off.
