INTRODUCTION

This page documents the configuration of a Linux Server (Mandriva 2008.1) and Windows XP Pro clients for establishing an ipv4 tunnel to a tunnel broker and providing ipv6 capability to the Local Area Network (LAN).

• We have registered for ipv6 addresses at an IPv6 Tunnel Broker (cache) and have been allocated the "Routed IPv6 Prefixes" of 2001:470:d:3ff::/64 and 2001:470:f0bd::/48.
• We've also configured a script to enable ipv6 connections on our server and LAN by establishing a IPv6-in-IPv4 tunnel (sit device) to the tunnel broker.
• We've installed RADVD to advertise prefix 2001:470:d:3ff:1::1/64 on the server internal (eth1) interface so clients on this interface is allocated ipv6 addresses.
• Service Pack 3 for Windows XP Pro is installed so that the "Microsoft TCP/IP version 6" protocol can be used to enable ipv6 capability on the LAN clients.
