RE: newbie questions: windows and ipv6?

Title: newbie questions: windows and ipv6?

We have deployed dual stack via tunneled service in our

office. We have both WinXP SP2 and WinServer2003 running

both stacks with no problems. We have even used the MS

DNS server for dual stack at one point, and it worked ok.

You don't really use DHCP for address assignment currently

with IPv6 (in most cases) - use stateless autoconfig (this

requires something running a "Router Advertisement Daemon"

somewhere in your network, usally a router, could be a

firewall (always is a multi-homed host, I believe).

 

We set up an OpenBSD based firewall / tunnel / RA daemon

using notes found on the Internet (search with Google - not

hard to find). That simplified things a lot.

 

I don't think W2K supports IPv6, or if so, it is very limited.

 

For help with IPv6 on MS, see their excellent book from MS

Press, "Understanding IPv6" - pretty much everything you need

to know is in there. Some things may be a bit dated, as it came

out before SP2 (e.g. you don't have to install IPv6 stack the old

way, just install it as usual for a new protocol).

 

You will find Windows generates "link local addresses" which

are a bit confusing (start with FE80, must include the interface

number, such as "FE80:1234:5678:9abc::17%4" - where the

last 4 is the interface number. Much better if you have an RA

daemon somewhere and have stateless autoconfig help all

nodes to learn the prefix and generate "unicast" addresses,

such as "2001:ec8:4008::1" - these are equivalent to static

external addresses in IPv4 (kind of). No interface ID is required

when specifying unicast addresses, and they will route to the

outside world (link local ones won't).

 

e.g. "ping fe80:1234:5678:9abc::17%4" and "ping 2001:ec8:4008::1"

 

BTW, never put link local addresses in DNS - it won't accept the

interface ID syntax, anyway.

 

How to find the interface ID for a given address? Easy but dumb

way is to try sequential IDs (1,2,3,4,5) until one works.

 

Easy way to get an RA daemon going? Deploy a Cisco router

with IOS 12.3 or later, and configure it for IPv6. If you are an

open source fan, build a router from FreeBSD, OpenBSD, even

Linux - there are RA daemons for all three. Lots cheaper than

a nice Cisco router.

Subject: newbie questions: windows and ipv6?

hi!
i'm new to this mailing list and i'm currently trying to set up a lab (for my
master thesis) where i want to migrate a "usual" small-company network to
ipv6.
my problem: i have to use microsoft for some services. (W2k advanced server
and one w2k client, 2 wxp clients)

i migrated dhcp (dibbler), dns (bind9), ntp, radvd, .. everything works fine,
but i cant find information on migrating

--> file shares made on a windows environment
--> active directory (possible? not on w2k i guess, but what's with w2k3??)
--> anyone else having the problem: i cant access ipv6 websites from a w2k
environment, works fine on wxp; (using firefox, 1.0.6 )

does anyone have experience with these services or does anyone have a good
idea/hint/tutorial/book/whatever? *g*

thanks sooo much!
