+config WAN_ROUTER
+ tristate "WAN router"
+ depends on EXPERIMENTAL
+ ---help---
+ Wide Area Networks (WANs), such as X.25, frame relay and leased
+ lines, are used to interconnect Local Area Networks (LANs) over vast
+ distances with data transfer rates significantly higher than those
+ achievable with commonly used asynchronous modem connections.
+ Usually, a quite expensive external device called a `WAN router' is
+ needed to connect to a WAN.
+
+ As an alternative, WAN routing can be built into the Linux kernel.
+ With relatively inexpensive WAN interface cards available on the
+ market, a perfectly usable router can be built for less than half
+ the price of an external router. If you have one of those cards and
+ wish to use your Linux box as a WAN router, say Y here and also to
+ the WAN driver for your card, below. You will then need the
+ wan-tools package which is available from <ftp://ftp.sangoma.com/>.
+ Read <file:Documentation/networking/wan-router.txt> for more
+ information.
+
+ To compile WAN routing support as a module, choose M here: the
+ module will be called wanrouter.
+
+ If unsure, say N.
