Sorry to reiterate, but does that include traffic encapsulated in a Teredo tunnel? Both inbound and outbound? Thanks.
Hi PaulC, With Teredo, IPV6 is encapsulated within IPV4 UDP packets. So yes, Teredo can be filtered, but you would need to set a raw rule to correctly check the header. (I dont have a (captured) teredo packet at hand, so cannot give you more info at the moment). - Stem
