Sometimes, mainly in servers, is better to disable ipv6 privacy extensions so that the configured ipv6 address is the only one configured on the firewall rules or the only one that shows up in the logs.
netsh int ipv6 set int Ethernet0 managedaddress=disable netsh int ipv6 set int Ethernet0 routerdiscovery=disable
After this configuration you will need to configure the ipv6 address and default gateway settings, because the OS will loose them.
To show the newly configured interface issue the fallowing command:
netsh interface ipv6 show int Ethernet0
You will see the following interface parameters disabled:
... Router Discovery : disabled Managed Address Configuration : disabled ...
To show global parameters use:
netsh interface ipv6 show global
Global Parameters example:
