< Overview of the file >

Of course everybody has a bit different /etc/fstab file because the partitions, devices and their properties are different on different systems. But the basic structure of fstab is always the same. Here's an example of the contents of /etc/fstab:

20.	Submitted by Andy Bloss If the VPN server is behind a router, Port Mapping will need to be done on the router. Standard port usage is 1723 for PPTP.  You might also need to configure your router for PPTP Passthrough. Port usage for IPSec is 500, 50-51. These ports will have to be forwarded to the VPN server's IP

For the Small Office/Home Office (SOHO), Windows XP Professional VPN features are a real boon.

Traveling users with laptops or handheld computers will inevitably want files on the home network; you just can't bring everything with you. This is where the beauty of the Windows XP Professional computer connected to an always-on connection, such as DSL or cable modem, shines. That always-on link can be used to accept incoming VPN connections and allow your mobile users to access shared folders and files on your private network.
