It is a cable connection (i.e. the WAN port on the modem is a coaxial one) and not a DSL one. Maximum ingress rate is ~450kbytes/s which is what the modem syncs at. By using "test_WAN_dual-isolate__piece_of_cake.qos", "tc -d qdisc show" reports (enp0s13 is WAN, enp0s14 is LAN): -------8<-------- qdisc noqueue 0: dev lo root refcnt 2=C2=A0 qdisc fq_codel 0: dev enp0s14 root refcnt 2 limit 10240p flows 1024 =09 quantum 1514 target 5.0ms interval 100.0ms ecn=C2=A0 qdisc cake 8002: dev enp0s13 root refcnt 2 bandwidth 900Kbit besteffort dual-srchost nat rtt 100.0ms raw=C2=A0 qdisc ingress ffff: dev enp0s13 parent ffff:fff1 ----------------=C2=A0 qdisc fq_codel 0: dev ifb0 root refcnt 2 limit 10240p flows 1024 =09 quantum 1514 target 5.0ms interval 100.0ms ecn=C2=A0 qdisc cake 8003: dev ifb4enp0s13 root refcnt 2 bandwidth 3300Kbit =09 besteffort dual-dsthost nat rtt 100.0ms raw=C2=A0 -------8<-------- If one of the hosts on LAN is running bittorrent, bmon on the gateway reports: RX bps RXpps TX bps TXpps enp0s14 23.55KiB 303 402.87KiB 322 enp0s13 457.26KiB 369 25.04KiB 307 Setting the ingress rate at 1900kbps (instead of 3300kbps as above), "tc -d qdisc show" reports: -------8<-------- qdisc noqueue 0: dev lo root refcnt 2=C2=A0 qdisc fq_codel 0: dev enp0s14 root refcnt 2 limit 10240p flows 1024 =09 quantum 1514 target 5.0ms interval 100.0ms ecn=C2=A0 qdisc cake 8008: dev enp0s13 root refcnt 2 bandwidth 900Kbit besteffort dual-srchost nat rtt 100.0ms raw=C2=A0 qdisc ingress ffff: dev enp0s13 parent ffff:fff1 ----------------=C2=A0 qdisc fq_codel 0: dev ifb0 root refcnt 2 limit 10240p flows 1024 =09 quantum 1514 target 5.0ms interval 100.0ms ecn=C2=A0 qdisc cake 8009: dev ifb4enp0s13 root refcnt 2 bandwidth 1900Kbit =09 besteffort dual-dsthost nat rtt 100.0ms raw=C2=A0 -------8<-------- Using bittorrent, bmon on the gateway reports: RX bps=C2=A0 RXpps TX bps =09 TXpps enp0s14 19.25KiB 219 232.51KiB 184 enp0s13 393.36KiB 304 20.25KiB 220 In both cases the ingress rate limit on the WAN interface (enp0s13) is not obeyed. I verified these data by using tcpdump and doing an IO- Graph with wireshark. Looking forward to your feedback, George
