      Hi everyone,

      I am running pfsense 2.4.4-RELEASE-p1 on a small Zotac Box with an Intel i3.
      My WAN interface connects via PPPoE on IPv4 to ISP (Telekom Germany) via the Connectbox (some Zyxel box that is on Bridge mode) and receives an IPv6 address via DHCP6.

      This is functional so far, but infrequently we are getting disconnects and I can not figure out why these are happening.
      I assume it has something to do with the DHCP6 assignment.

      These are the logs from the most recent disconnect event.

      In this case it recovered after a short moment, but this was not always the case in the past.

      If needed I can also post the rest of the log that contains the successful re-connection.

      Any help would be greatly appreciated, because my next move would be to just not have IPv6 anymore, which I would like to avoid.
