In this chapter, we covered different forms of traffic shaping and introduced the pfSense traffic wizard. While the wizard is helpful in getting started using traffic shaping, this chapter showed some of the limitations of the traffic shaper. It also showed that creating queues and editing/creating our own traffic shaper rules is not that difficult. We also saw that limiters can sometimes be helpful in allocating bandwidth. We provided some concrete examples of implementing traffic shaping; finally, we covered what to do when traffic shaping doesn't work as it should.

In the next chapter, we will continue to build on our knowledge base and cover a subject that you are likely to encounter repeatedly, both with pfSense and in networking in general: virtual private networks (VPNs).
