New PPPoE backend, some feedback
-
Yeah that config delay seems odd. I'd expect that to be close to instant really. Though I guess some part of he upstream server might be delayed at the backend.
But the important part there would be whether or not it does eventually connect.
The old mpd5/netgraph pppoe client also shows as up if it's parent NIC is linked but if_pppoe, currently, shows as 'up' at all times one the interface is created. That's confusing the status page. It does seem like we could improve that relatively easily by including the connection state info there.

Try setting
Start DHCP6 client in debug modein System > Advanced > Networking.It's not clear from your dhcp logs whether or not it's actually running on pppoe0.
Also you can filter that log by the dhcp6c process. Everything else shown there isn't relevant.

I did ponder that but pfSense asks the question and the upstream responds immediately with the correct Ack. There is nothing different in the multiple upstream server responses, even at the final time where pfSense stops asking, seemingly satisfied with the last repeated Ack.
Is there any chance the almost-paired PPP IPCP and PPP IPV6CP Requests are stepping on or resetting each other's almost-paired Acks?
In effect:
Request, Request, Ack, Ack = not good, loop continues
Request, Ack, Request, Ack = goodOnly the sequencing changes for the final accepted Acks, not the response Ack data. I know it shouldn't matter but it is the only difference I can find:

in the end there seems to be a response from pppoe but the gateway DHCP6 is still 'waiting'
the full 'grep dhcp6c /var/log/dhcpd.log' is too long to post

Hmm, interesting!
I note that in that last request it asks for a different IPaddress. But then connects and stars using the IP the server had been passing it in the previous request/acks.

That looks like it's completing as expected. You see the prefixes added to the internal interfaces?
Do you see the gateway in the NDP table?
Does that exact same config work when not using if_pppoe?

Apart from the very first request (where it uses 0.0.0.0.) it uses my static IPv4 address, which is obtained via DHCP. The oddball IP you see at the end of the PCAP is the IPv4 of the upstream PPPoE server (it picks from a list of 5 or 6 possible addresses).

WANix1 is the WAN interface (ix1 for intel 10g sfp+ nic1, nic0 is internal)@stephenw10
while the gateway says its 'waiting' the local computers get ipv6 connection now, and probably before as well. NDP table looks fine. I concluded 'it's not working' based on the status/gateways overview.so the real question should be, why doesn't the gateway show as active?

No, until the upstream PPPoE assigns my static IP via DHCP the firewall has no idea of my IP address.
I've no idea why my ISP likes to issue my IPv4 address dynamically rather than have me fat-fingering it in myself.

Hmm, your ISP is doing DHCP over PPPoE? For IPv4? I don't think I've ever seen that if so.

Probably my poor choice of terms Steve. The ISP dynamically sets my WAN IP address (albeit my IPv4 address is static) as part of the PPPoE connection process. For most UK residential customers they will have a dynamic WAN IP address assigned by the ISP on connection (PPPoE or DHCP) and this will periodically change, including on reboot etc.
Whilst we use different terms on routers between DHCP and PPPoE connections a PPPoE connection can still (and usually does in the UK) have a form of dynamic host configuration. This is sent by the upstream PPPoE server down to the router, which is effectively now a PPPoE client, including the dynamically assigned IP address(es) as well as the other network parameters.
For PPPoE connection the dynamic host configuration comes immediately after the CHAP, triggered by the Configuration Request with the dynamic host configuration coming back on the Ack (dynamic options, IP address to use, DNS info etc. Sometimes it is referred to as the PPP IP Control measures but it is a bit broader than IP address control alone.
You and I both use PPPoE over the BT/Openreach infrastructure so presumably there are few (if any) significant differences between our connections, even though I have a different ISP.
There are many ways to describe things but this one is mine so only subject to my errors!
️ -
Ah OK, good. For a minute there I thought you had some weird edge case connection.
Yes, AFAIK almost all UK ISPs use the same low level infrastructure. Certainly if they are not LLU providers, like Sky for example.
Then it seems like I should be able to hit it given enough poking....
-
I think this is awesome this has been developed, thank you to everyone who has contributed to it. I think in the UK it will be especially appreciated as almost all ISPs are wanting to keep using PPPoE instead of IPoE.

Try this. Run:ifconfig pppoe debugThen try to reproduce the connection issue. Check dmesg for any additional error logs whilst is fails to connect.

All done. I will email you a clean connection from a reboot and a 'failed' but ultimately reconnected pppoe0 interface down/up event.
Nothing of note in the reboot logs (to my eyes at lease) but disconnecting / reconnecting from the interface page produced lots of this (plus GUI hangs, server not responding etc):

Updated the latest public beta (25.03.b.20250429.1329) but no change in the symptoms or the GUI presentation of the true interface status.I captured system logs and dmesg but nothing notable against the previous ones. It took a few retries to get itself going again.
