Re: Bypassing ISA Server 2004 with IPv6

["Thor (Hammer of God)" <thor () hammerofgod com>]

The "no excuse" is binding IPv6 to the adapters in the first place and
expecting an IPv4 app to filter it.   ISA doesn't filter NetBEUI either...
So, don't bind NetBEUI to the adapter, or better yet, if you do, don't
expect it to be filtered.
