| 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. |
| 15 | |
| 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 <ftp://ftp.sangoma.com/>. |
| 23 | Read <file:Documentation/networking/wan-router.txt> for more |
| 24 | information. |
| 25 | |
| 26 | To compile WAN routing support as a module, choose M here: the |
| 27 | module will be called wanrouter. |

| 29 | If unsure, say N. |
