 By contrast, QoS analyzes all traffic and follows rules for prioritizing one //type //of traffic over another, based on all clients on the network. In a sense, Bandwidth Limiter is a more crude tool, whereas QoS might be considered a little more refined.
-Confusingly, Bandwidth Limiter shares a few settings with QoS. When Bandwidth Limiter is enabled, QoS should be disabled, and vice versa. If both are enabled, they will conflict with each other and neither will work. Also, Bandwidth Limiter may not work if you enable some IPv6 service types, such as 6in4. The latter use encrypted tunneling protocols, incompatible with Bandwidth Limiter.
