In addition to a really good firewall Linux has a builtin advanced routing and traffic shaping (lartc).
There are many applications (firehol, firestarter, etc) to make the creation of iptables firewall easier, what similar to tools exist to make working with the policy routing and traffic control easy?
I think wondershaper is the canonical tool for simple traffic control. Beyond that (more complicated uses), I haven't found anything easier than just reading the docs and writing my own scripts.
There are some linux-based traffic shaping appliances (rackmounted boxes) around that have (older, less featureful) open source software available. Sorry, I can't recall the product name just now. But yes, there are nicer options than a simple script.
