Description

After what is probably a short communication hick up, the GUI IPV6-WAN-status stays "Offline, Packetloss"
I noticed this issue at least five times. Luck-ally it only seems to be the GUI-status. Luckily the real traffic seems to be OK.

What happens:
- at certain moment pfsense detect that the GW is gone (see alarms below)
- the communication returns (a ping shows that the GW is back again)
- however the GUI keeps the error state for ever
- so the gateway status return is not properly detected by pfSense

I did setup a syslog server (graylog) in order to fetch all potential related alarms.

In the logging I found messages which draw my attention. when filtering the log using message like "ppp"

Using the time as new selection criteria I selected the alarms occurring around this time. Starting and ending with an alarm which IMHO is not related. Here they are:
