Greetings everyone.

I've been messing with trying to understand and subsequently configure, the OpnSense Shaper for a while now.  I would chalk it up mostly to my unfamiliarity with firewalls in general, but also not really understanding what needs to be prioritized.

I work from home, and one day my throughput went to crap.  Turns out one of the kids was downloading a new game.  All of a sudden I know what to prioritize. :)

I found a thread that got me started here, https://forum.opnsense.org/index.php?topic=48936.0

With all the threads/questions regarding the Shaper, I figure I'd post my config here.  So if it helps someone, cool.  If not, cool too.

Something to note; the upload rule needed Firewall > Settings > Advanced > Shared Forwarding set to enabled (checked).

Something ELSE to note; your Windows config can also lead to a bad bufferbloat score.  For example, I moved my laptop (on wireless) from a C- to an A+ with the following command;

  netsh int tcp set global autotuning=disabled

Of course, ymmv.

BufferBloat

Sorry, the pic is too large for upload, so I had to use this file format.  It's A+, but the bottom is the impressive part.  There appears to be minimal difference between the three tests.
