Routing Windows 2000 IPv6 traffic

Your IPv6 network prefix: 1:2:1:1::/64

Now you're ready to set up the tunnel.

Configuring the Router -> Broker Tunnel

Using the values provided by the broker, configure the tunnel from the router

to the broker. You'll want to do something like:

ifconfig gif0 giftunnel

ifconfig gif0 inet6 1:1:1:1::2 1:1:1:1::1 prefixlen 128 alias

route -n add -inet6 default 1:1:1:1::1

HE provides lines similar to the above. Substitute your IP addresses where appropriate.

Configuring the Router LAN Interface

Using the network prefix provided, configure the LAN interface for IPv6:

ifconfig xl1 inet6 1:2:1:1::1 prefixlen 64 alias

Some people may prefer to use the current IPv4 address as an identifier, instead

of the ::1 used above. This is more or less dependent on the address space assigned

to you (though in our case it would work), and may make the IPv4 -> v6 conversion

a little easier to maintain. E.g. we might have configured xl1 as 1:2:1:1::

Interestingly, OpenBSD and Windows have already configured their interfaces,

deriving a "link local" address from the ethernet addresses on the cards. This

address is used below when configuring the default IPv6 route under Windows.

Configuring the Windows LAN Interface

Assign a default route and IP to the "Local Area Connection" Windows interface:

ipv6 rtu ::/0 5/fe80::260:97ff:fea0:ebe5 pub

ipv6 adu 5/1:2:1:1::2

In this case, the LAC interface number is 5 (denoted by the 5/ above). To determine

your LAC interface, type "ipv6 if" from a DOS prompt. Also note that if you named

your network interface something other than the default "Local Area Connection",

that name will be used in its place in the "ipv6 if" output.

Note that we are setting the default route to the "link local" address of the

router. This address can be determined with "ifconfig xl1" on the router. The

address will start with fe80::.

Testing IPv6

From the router, ping the broker's end point:

ping6 1:1:1:1::1

From the Windows machine, ping the router:

ping6 1:2:1:1::1
