Floating WAN Firewall RuleAfter then nth time of suffering stuttering during a conference call on my wired connection, I stumbled on to the (common-but-undiagnosed) issue of “buffer bloat” (or “bufferbloat” – whatever spacing floats your boat).
The linked article certainly opened by eyes to the issue via a linked test site, with clear “before” and “after” improvements…
For my own (future) reference in implementing such fixes on pfSense…
For details, please do read through the linked article, but otherwise, the summary steps for pfSense are:
Create Download and Upload Limiters
Navigate to Firewalls > Traffic Shaper > Limiters and create (1) a download and (2) upload limiter.
Download Limiter
Upload Limiter
Under the two newly added limiters, create a corresponding (1) download limiter queue and (2) upload limiter queue.
Download Limiter Queue
Upload Limiter Queue
Last but not least, create a floating firewall rule from Firewalls > Rules > Floating:
Floating WAN Firewall Rule
After restarting the entire pfSense box, test again!
