INTRODUCTION

This is a set of utilities and shell scripts you need in order to be able to
use Linux kernel-level WAN Router.  Please read WAN Router User's manual
(router.txt) and WANPIPE driver documentation found in /usr/lib/router/doc
directory for installation and configuration instructions.

You can find the latest version of this software in /pub/linux directory on
Sangoma Technologies' anonymous FTP server (ftp.sangoma.com).

ACKNOWLEDGEMENTS

This product is based on the WANPIPE(tm) Multiprotocol WAN Router developed
by Sangoma Technologies Inc. for Linux 2.2.x.  Success of the WANPIPE
together with the next major release of Linux kernel in summer 1996 commanded
adequate changes to the WANPIPE code to take full advantage of new Linux
features.

Instead of continuing developing proprietary interface tied to Sangoma WAN
cards, we decided to separate all hardware-independent code into a separate
module and defined two levels of interfaces - one for user-level applications
and another for kernel-level WAN drivers.  WANPIPE is now implemented as a
WAN driver compliant with the WAN Link Driver interface.  Also a general
purpose WAN configuration utility and a set of shell scripts was developed to 
support WAN router at the user level.

Many useful ideas concerning hardware-independent interface implementation
were given by Mike McLagan <mike.mclagan@linux.org> and his implementation
of the Frame Relay router and drivers for Sangoma cards (dlci/sdla).

With the new implementation of the APIs being incorporated into the WANPIPE,
a special thank goes to Alan Cox in providing insight into BSD sockets.

Special thanks to all the WANPIPE users who performed field-testing, reported
bugs and made valuable comments and suggestions that help us to improve this
product.

  separately
