| ---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/>. |
| |
| To compile WAN routing support as a module, choose M here: the |
| module will be called wanrouter. |
| |
| If unsure, say N. |
