So, the time has come to retire our old Windows 2003 server. This box runs bookkeeping software (Exact Globe 2003, and BCS Delta), and is exclusively used internally by the administrative staff.

The first thought that came to mind: since we're running several Linux servers already on IPv6-only, would it be possible to run a Windows server also on IPv6?

While Windows Server 2012 has been released recently, we can not use it (yet), because the latest version of Windows that our current VMware setup (ESXi 4.1) supports as guest OS is Server 2008 R2.

So we'll go for 2008 R2 and give it a shot.

Basic functions

A dedicated VLAN was created for IPv6-only systems, so that building, testing and configuring would not interfere with any production networks. Configuring this VLAN with only IPv6 allows to use simpler IP Access Control Lists (ACLs), and start from scratch:

interface Vlan9
 description IPv6_only_Servers
 no ip address
 no ip proxy-arp
 ipv6 address 2001:610:148:BAD::1/64
 ipv6 nd prefix 2001:610:148:BAD::/64
 ipv6 traffic-filter ipv6_servers2_out in
 ipv6 traffic-filter ipv6_servers2_in out
end
