Why Does UAG DirectAccess Require Two Public IP Addresses?

I’ve wondered why UAG DirectAccess requires two public IP addresses and have asked Tom about it in the past. Like most husbands, he gives me a short answer hoping that I’ll stop asking him questions Smile   The answer I always got from him was that the two consecutive public IP addresses are required to support Teredo.

OK, that’s cool. But how are these addresses used by the DirectAccess client Teredo adapter? Check out this Edge Man article to find the answer.
