   9          Wide Area Networks (WANs), such as X.25, frame relay and leased
  10          lines, are used to interconnect Local Area Networks (LANs) over vast
  11          distances with data transfer rates significantly higher than those
  12          achievable with commonly used asynchronous modem connections.
  13          Usually, a quite expensive external device called a `WAN router' is
  14          needed to connect to a WAN.
  16          As an alternative, WAN routing can be built into the Linux kernel.
  17          With relatively inexpensive WAN interface cards available on the
  18          market, a perfectly usable router can be built for less than half
  19          the price of an external router.  If you have one of those cards and
  20          wish to use your Linux box as a WAN router, say Y here and also to
  21          the WAN driver for your card, below.  You will then need the
  22          wan-tools package which is available from <>.
  24          To compile WAN routing support as a module, choose M here: the
  25          module will be called wanrouter.
  27          If unsure, say N.
