I've setup a NAT gateway with Asterisk and such, and am up to the stage of getting Quaility of service working. I'm following along in this article http://www.howtoforge.com/voip_qos_traffic_shaping_iproute2_asterisk and having trouble understanding what these mean 0x02: Minimize Monetary Cost 0x04: Maximize Reliability 0x08: Maximize Throughput 0x10: Minimize Delay Perhaps examples would help. And although a great article, it could be expanded on much more, such as what IProute2, tc, qdisk and such do. While I'm here, might there be a web interface such as ntop that could handle this better? one that works just as well as doing on via command line.
