In this chapter, we discussed routing and bridging, and the fact that while conceptually they are different, they often create the same issues; for example, in both cases we must take care to make sure looping does not take place, and both often involve firewall rule configuration. We discussed both static and dynamic routing, including policy-based routing, and covered four pfSense packages that implement dynamic routing: RIP, OpenBGPD, Quagga OSPF and FRR. We discussed how to implement bridging in pfSense and some of the issues associated with it. Finally, we covered troubleshooting for routing and bridging.
In Chapter 11, Extending pfSense with Packages, we will cover in greater depth something which we have already hinted at already: the extent to which pfSense's functionality can be enhanced with the addition of third-party packages.
