Sadly, the traffic shaping/limiting part of pfSense is plain unusable by ordinary users. Lot of effort required into producing working wizards for common scenarios, or even a simple checkbox. People should not have to deal with manual configuration of this thing normally, since they usually end up with completely broken setup, or a setup that has no effect at all. Way too many features, way too complicated and very hard to understand. No amount of convoluted, techblurb docs is going to change this.
