Use manually assigned ipv6 address

  • 772

I have a /48, and from this I assigned a /64 to this lan

I have a windows 8.1, which I want to use an assigned ip for outgoing adress.

But I keep getting an automatically assigned address.

netsh interface ipv6>show addresses


Interface 2: Ethernet

Addr Type  DAD State   Valid Life Pref. Life Address
---------  ----------- ---------- ---------- ------------------------
Manual     Preferred     infinite   infinite 2001:DB8:1234:8000::1111:2222
Public     Preferred  29d23h53m20s 6d23h53m20s 2001:DB8:1234:8000:21d:9ff:fe24:656c
Other      Preferred     infinite   infinite fe80::21d:9ff:fe24:656c%2

(2001:DB8:1234:: is the docummentation example network)

I only want the 1111:2222 adress ised as outgoing, not the one generated from the mac. (I want to use this as a first level access-control)

I have disabled privacy extensions:

netsh interface ipv6>show global

    These instructions on http://blog.yogi-way.lv/2013/01/ipv6-and-slaac.html are probably what you need:

    To disable SLAAC in Windows first check what NIC you would like to disable auto configuration on with:

    netsh interface ipv6 show interface

    Then execute

    netsh interface ipv6 set interface X routerdiscovery=disabled

    where X is desired interface index from the show command output.

    To disable privacy execute (command works globally for all interfaces):

    netsh interface ipv6 set privacy state=disable store=persistent
netsh interface ipv6 set global randomizeidentifiers=disabled store=persistent

    One warning though: if you disable listening to router advertisements you'll have to configure the IPv6 default gateway (and maybe some other settings like MTU size) manually.
