Hi all,

I've been struggling with this for about a week now, have tried googling for all of the tutorials and guides I can find and still not having any luck with this! I've upgraded from an Asus router to OPNSense to get some more control over a dual WAN setup but having trouble configuring my PPPoE connection.

Im using a UK ISP (Ghost gaming broadband, a subsidiary of structured communications) which has a PPPoE WAN connection. This worked fine on my previous router after inputting username/password

My setup is a draytek vigor 130 into the OPNsense box and then out to a mikrotok switch. The modem is configured in bridge mode according to: https://draytek.co.uk/support/guides/kb-vigor-130-bridge and it successfully connects to the VDSL.

OPNSense is on a brand new defaults, LAN is working fine and I can get into the interface etc, all good. WAN is set in interface assignment as per:

PPPoE config:


This gives in the overview, an "up" status, with 0 uptime and no packets transferred, no Mac address and the incorrect 1500 MTU:

There's also only a wan_dhcp6 gateway that appears as online but again with no data.

I've tried various guides and changing settings with no luck and I can't see where I've gone wrong with this as most guides seem to move along the lines of set PPPoE and out the user and password in and it works!

Thanks in advance for any help, and please let me know if there's any more config screens that would be useful.

It should just work. Try deleting the pppoe interface and adding it again from stratch.

It just works is generally what I've found from most sources, unfortunately it doesn't!

I've tried readding and rebooting and all the other kinds of turn it off and on again with various different settings and unfortunately no luck.

I've checked with the ISP and they said settings all look ok but they've not seen any radius attempts from their side.

I also don't see anything PPPoE related in any logs (although happy with some directions to check the right ones/what to look for!) So it seems like it's not even attempting to make that connection for some reason

Interfaces, Point-to-Point, Log File

Thanks for the pointer, not sure how I missed that!



Not sure if someone else can make something of one of the details but it seems like it just can't see a link to try the PPPoE connection? The one thing that stood out to me was connecting to '' like something is misconfigured/missing a name somewhere.

Just tried running the command from here: https://www.reddit.com/r/PFSENSE/comments/gpm7tz/pppoe_weird_issue/

As it sounded like a very similar issue, but the same loop persists.

Oh I also tried swapping the ethernet port as it's a dual NIC card, same problem but the message in pppoe changes to connecting to '1' so it seems that is related to the interface numbering and 0 is ' '

It looks like this might be a rare Draytek Vigor 130 failure. I tried changing interfaces, anything I could find related to PPPoE re-connect loops on the net and nothing worked. I tried resetting the Vigor 130 and it wouldn't pick up a VDSL connection again, it was looking for ADSL on the auto setting and forcing VDSL lead to constant training status. So I dug out an old Openreach modem I wasn't even sure would work, and PPPoE connected straight away.

Hi Praelia7or,

Please check your Modem. Attached you can see my DSL status when it is synchronized with my ISP.

If your modem WebUI looks similar I would assume the modem is working fine. Since you are already on a phone call with your ISP, this is very likely.

If the modem gets synchronized it is very unlikely that the modems hinders to establish the connection.

My OPNsense is installed on an embedded system (for details see https://pcengines.ch/apu4d2.htm). I did some tries to get OPNsense running in a way it is configurable and working.

All my failures ends after I executed the installation wizard during each installation process.

Kind Regards
Thomas
