<![CDATA[Traffic doubling in monitoring]]>I made a thread about this some time ago, and we never did come to a conclusion on how to fix it but i think i've now got enough info on how to reproduce it that it might be helpful to dev team.

I am using Version 2.6.0-RELEASE (amd64) in an esxi host

The problem
the monitoring tab shows double traffic (the right side panel is correct, the monitoring tab is not)

steps to reproduce

this was the bit I couldn't really figure out, as it also seemed to sometimes work and sometimes didn't but I think i've nailed it down now.

  1. assign FQ_CODEL limiter rules (floating rules)
  2. if you host an external service which requires port forwarding, assign those rules + FQ_CODEL rules to the interface (VPN in my case)
  3. let traffic flow and watch as you get the situation I experience.

This behaviour didn't exist in 2.3 and everything worked as it should.

Removing #2 does 'resolve' the issue but then you either get left without port forwarding or without FQ_CODEL. Floating rules alone are not sufficient to implement FQ_CODEL in this scenario as i detailed in https://forum.netgate.com/topic/174326/fq_codel-only-working-on-downstream

Using the steps above, you should be able to reproduce this bug from a vanilla install.
