Need to Skip counting specific traffic from counters

Hello, My question may be bit silly but still i want to ask

My scenario is

i have a mikrotik router and a nas attached to it
i have connected to a third party radius to via web for restricting data usage per day.
some of the users just copy files from the nas and the data usage gets counted in the radius

I want to skip the specific data requests from the nas should not be counted in radius.
is this even possible to implement

Please explain what the setup is of “i have connected to a third party radius to via web”

When do users authenticate to the radius?

  • ethernet Dot1X ?
  • wifi WPAx/Enterprise?
  • Hotspot authentication via hotspot portal with RADIUS users?
  • other path?

Where are you counting?
-RADIUS accounting?
-Hotspot limits?

Hotspot has some possibilities :

I have connected Hotspot authentication via hotspot portal with RADIUS users

And i do know about walled garden setup
It would pass traffic without needing to authenticate hotspot.
But would it also skip counting traffic for the specific destination.


Any help very appreciated.
