However, I think you need to adjust your bandwidth and = overhead settings, otherwise Cake isn=E2=80=99t reliably in control of = the bottleneck queues. Try these to begin with: =E2=80=A6 bandwidth 850Kbit conservative dual-srchost nat =E2=80=A6 bandwidth 15Mbit conservative dual-dsthost nat ingress That should give you correct operation, and you can fine-tune from = there. - Jonathan Morton
