I recently set up an IPv6 Tunnel with tunnelbroker.net.
I was really underwhelmed with what I found with IIS 2012
Disabling ICMPv6 - There was nothing to disable echo requests only. Disabling ICMPv6 completely broke IPv6 access.
Vulnerable ports left open. Doing an IPv6 Port scan from the link below shows ports such as 445 being open, even though there were blocking rules in place.

Scanning on a PC protected by Windows Firewall instead showed all ports as Stealthed.
Am a missing something or do I need to add special rules for IPv6?
