  2. ##MODIFIED VERSION of FreshJR_QOS v1.9 for MedWatt released 07/17/2017
  3. ##Modified version has bandwidth limiter enabled for LAN IP's 192.168.1.32 - 192.168.1.47
  4.  
  5. ##Script Tested on ASUS AC-68U, FW380.67_beta4, using Adaptive QOS with Manual Bandwidth Settings
  6. ##Script Changes Unidentified Packets QOS destination from "Default" (Category7) Traffic Container into user definable (in WebUI) "Others" Traffic Container.
  7. ##Script Changes Maximum Allowed Bandwidth of Default Traffic Container (Category7). This container is now repurposed to act as bandwith limiter for defined clients.
  8. ##Script Changes Minimum Guarenteed Bandwidth per QOS category from 128Kbit into user defined percentages upload and download.
  9. ##Script supports custom QOS rules
  10. ## Included active custom rule moves any TCP/UDP traffic on ports 500 & 4500 into VOIP traffic Container. (Wifi Calling)
  11. ## Included active custom rule moves any TCP/UDP traffic on ports 16384 - 16415 into VOIP traffic Container. (Facetime)
  12. ## Rest of rules are commented out but are present to act as custom rule templates. See comments next to rule for details
