PPPoE issues since 2.4

[Sysyphus]

You need to setup an outband NAT in pfSense to access the modem - Click here

Once you logon to the Vigor 130 modem, you will be at the dashboard, you will see the uptime in hours-minutes-seconds,another point is to make sure that you have the most up-to-date firmware.

From the dashboard you can navigate on the left to Online Status -> Physical Connection

Additionally, from a telnet session to the Vigor 130, type the command:  show status

The first line of the output will show the uptime

Uptime is how long the Vigor is running, it is not affected by the DSL sync.

You can send syslog messages, with DSL information, to a device on your network, then you can filter them and see when DSL goes through a resync.

I would run a tcpdump (Diagnostics->Packet Capture) on the WAN interface of the pfSense while this fault is happening.

Posting that to a pastebin where we can look at it would be helpful (you'll have to scrub any passwords etc, be careful here before just blindly pasting)

Thanks for the reply's.

Been very busy the last week and most of next week.

Will have to put up with it for awile untill I can try out your suggestions and get the log files.

Just posting an update.

I had some time last weekend and decided to rebuild my router and do a fresh install with 2.4.

Only change i made from my old setup was to enable IPv6 on the BT connection right from the start during the PPPoE setup.

So far my connection has been up for 6 days.

My guess would be something got messed up when i upgraded to 2.4 from 2.3. As in it was trying to use the IPv6 even though it was disabled.

Thanks for all your help and suggestions.

Just had a same issue with "IPV6CP: rec'd Configure Ack" messages appearing even though IPV6CP is disabled on the WAN interface.

It didnt appear again on the PPPoE reconnect.

And you are seeing PPPoE disconnect?

[IssueHaver]

This probably happened on/after daily PPPoE reconnect. Everything worked normally except the DDNS client that didn't update properly (different issue: https://forum.netgate.com/topic/142719/ddns-client-skipped-ip-update/5). But I dont know why I have IPv6 messages on an interface where IPv6 is disabled.
After reconnecting PPPoE WAN again, the messages didnt start appearing again.

[stephenw10]

If the ISP supports v6 is may have sent that ACK in repsonce to a config request. If your interface is not configured for v6 it would just have ignored it.
Unless you are actually seeing a connections problem there I would ignore that. I looks like a harmless response.
