Chapter 4. Client
Now we examine the client end. In practice, when used to allow access
to a remote network, this box can easily serve as a Samba (Windows
Networking) server, DHCP server, and even an internal web server. The
important thing to remember is that this box should be as secure as
possible, as it runs your whole remote network.
First things first, you must have ppp available in your kernel. If you are
going to allow multiple machines to use the tunnel, then you need to have
firewalling and forwarding available too. If the client is going to be a single
machine, ppp is enough.
