| ---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. |
