OpnSense Shaper Outbound Rules are being ignored

Overview

Configuring OpnSense to prioritise traffic for certain protocols and packet types in an attempt to further reduce latency under load and buffer bloat it was noted that any rules that I created for traffic leaving the network (Asymetric VDSL connectio) were being ignored.
Attempts to change the rules to deliver the same functionallity from a different angle, equally no difference.
This was also not rule order / presidence - as all rules were returning zero for outbound traffic.

Environment

• OpnSense 23

Issue

• Using TRAFFIC SHAPER
• PIPES and QUEUEs are in place
• RULES are in place
• RULES for any traffic Outbound / Upload / Downstream are all being ignored.

Diagnostic Steps

• Using FIREWALL > SHAPER > STATUS
• Check the box to SHOW RULES
• Check the box to SHOW ACTIVE FLOWS
• On pressing the REFRESH button beneath the checkboxxes, the inbound / download / upstream columns increment, and the outbound / upload / downstream columns remain at zero.

Root Cause

• This only supports a single gateway.

Resolution

• Check to see if you have a group configured.
• SYSTEM > GATEWAYS > GROUP
• Removal of a historical configuration where a fall back was in place but now disabled, allowed the rules to work as expected.
