  2. ##FreshJR_QOS v1.92 released 09/07/2017
  3. ##Script Tested on ASUS AC-68U, FW380.67, using Adaptive QOS with Manual Bandwidth Settings
  4. ##Script Changes Unidentified Packet QOS destination from Default Traffic Container (Category7) into user definable (in WebUI) Other Traffic Container
  5. ##Script Changes Minimum Guarenteed Bandwidth per QOS category from 128Kbit into user defined percentages upload and download.
  6. ##Script supports custom QOS rules, to create rules copy applicable rule templates below, change filter parameters as desried, and then paste into custom rule start area.
  7. ##  Included custom rule moves any TCP/UDP traffic on ports 500 & 4500 into VOIP traffic Container.         (Wifi Calling)                 
  8. ##  Included custom rule moves any TCP/UDP traffic on ports 16384 - 16415 into VOIP traffic Container.      (Facetime)
