- # test_LAN_triple-isolate__piece_of_cake.qos (Cero3 Shaper)
- #
- # Abstract:
- # This is a one band cake and ipv6 enabled shaping script for Ethernet
- # gateways. This exists for the purpose of testing cake's different isolation
- # options, specifically the non-directional triple-isolate feature that promises
- # to finally tackle the bit-torrent hole in simple.qos.
- # This specific version is supposed to be used on LAN interfaces:
- # the script's ingress direction equals the internet/WAN upload direction
- # the script's egress direction equals the internet/WAN download direction
- #
- # NOTE: Shaping on a LAN interface only affects machines connected via that
- # LAN interface, so typically WIFI/WLAN traffic will not be shaped!
