Also check the Gateways log to see if apinger is biting you.

Yeah - On two seperate systems I tried two solutions.

System 1 that gave issues, I turned off gateway monitor.

System 2 I raised the thresholds of everything in the advanced gateway settings.

Both solutions worked fine. The second one allowed me to keep seeing quality graphs in RRD data.

Some cable modems will hand out a local private IP if they loose their upstream connection in order to access them and fix whatever problem exists. That's fine but pfSense receives that IP and never rejects it favour of a public IP when the connection comes back. What does Status: Interfaces: show when the WAN connection is lost?

Dec 5 18:00:27 apinger: ALARM: WAN_DHCP(68.0.32.1) *** down ***

Steve I will check status next time.

Thanks Jerry

Ok, so apinger is marking the connection as down. Check the system log for any interface UP of DOWN events like:

kernel: fxp0: link state changed to DOWN

That would indicate a local physical connection failure like if your modem rebooted.

If you don't see that, and it's not the cable modem local address problem, then it's probably apinger causing the problem. It may be a symptom rather than a cause but it's easy to test by disabling it. Go to System: Routing: Gateways: and edit the existing gateway. Check 'disable gateway monitoring'.

I turned off gateway monitor and has not failed .
Hope I can find time to learn more about PFSense.

Hmm, well there are some issues with apinger as you may have seen while searching for this error. Personally I've never had any problems with it. Hopefully this will be resolved when 2.2 is released.

Hmmmm…

Well - For me at least raising the thresholds very high worked just as well as turning it off.
That way when you really do have an outage it will do what its supposed to and you get to keep your pretty rrd quality graphs.

stephenw10

It may work just as well normally but will it come back up after an outage? With the threasholds set to their standard values if you have a laggy or lossy connection, such as a wifi or 3g/4g link, then you would exepct to see lots of alarms and down times but you still expect it to come back up by itself which this isn't. :-
I'll not pretend to know too much about apinger though it seems to behave in it's own special way. ;) I once read through all the config scripts and still came away with conflicting ideas.
