Quality graph shows 100% packet loss
-
my quality graph (Status -> rrd graphs -> quality) is showing 100% packet loss. i am running 1.2.3-RELEASE on dual machines synced together via CARP. i found a couple other topics regarding this. i do have a few packets per minute being denied by the default deny rule, the CPU usage is low, and my state table is only 0.25% used. the traffic that i have allowed works fine and i don't notice any issues with it, so i am unsure what this graph is telling me….
edit: oh, and i can also ping my gateway from the WAN interface just fine...

I'm also seeing the same - it was 'normal' until about November last year, but has been showing 100% packet loss ever since.
Also running 1.2.3-RELEASE.
The minimum figure shows as less ( e.g. 98.1% ). It's almost as if there's a 100% offset getting in to the calculation somewhere.

this happens usually when theres an issue with the gateway, not sure why it stays at 100% but heres how to fix it:
at a command line (ssh or the command prompt in webgui)
$config['interfaces']['wan']['use_rrd_gateway'] = 'x.x.x.x';
where x.x.x.x is your gateway ip
from the pfsense docs:

Thanks, I'll give that a try.
How does pfSense measure the quality? I can't ping the gateway IP (as reported under Status/Interfaces), but it must be ok as there are no routing issues !
Could my ISP changing the IP of the gateway cause the problem?
-
not sure exactly how offhand (its in the book) but it pings the default gateway every so often. if the gateway is changed it could.
-
Sorted it. The modem was giving pfsense the IP for the ISP gateway, which is not the same as the next hop gateway.
Normal operation has been restored :)
Thanks again for your help.
