WAN Traffic Maxed Out after Upgrading to 2.1.3
-
Since upgrading to 2.1.3 notice that the WAN traffic on the Traffic Graphs is totally maxed out whereas the LAN traffic is normal for the number of active users.
Any pointers as to what might be causing this or how to trace a possible cause?
I am using 2.1.3 on an Intel Atom D525 quad core device, squid (also caching windows updates), squidguard, and tried installing DarkStat to try identify source of the problem even though it is not giving me much more information than the traffic graphs.
Any help would be appreciated.

You could install the "iftop" package and watch that on the CLI to see the current bandwidth usage and from/to what IP?

Usually that's squid downloading in circumstances like you describe. Restarting the service should make it abort whatever it's trying to cache.

Thanks for the feedback. As recommended the SQUID package seems to have been refreshing the cached items maxing out all the bandwidth. After reviewing the custom options some recommended tweaks have resolved it as documented. https://doc.pfsense.org/index.php/Squid_Package_Tuning#Performance_Tweaks
