Summary
In this chapter we’ve covered some of the basics of using Linux as a router in normal-case scenarios. For the most part, using Linux as a router in normal LAN and WAN situations is a piece of cake because most of the work is done by the kernel and software automatically.
One of the things that Linux excels at is networking, so it’s nearly a no-brainer to pick Linux as the glue for your network even if the rest of your LAN or WAN consists of Windows, Mac, or other types of machines. Linux is kind of the great “uniter” of operating systems.
In later chapters we’ll cover more difficult routing tasks such as load balancing and VPNs in greater detail, which are tasks that used to be the domain of expensive hardware routers only.
