Seriously Microsoft, I’m starting to go right off you.
Forefront Threat Management Gateway 2010, your ISA Server replacement, your “Needs a 64-bit Operating System” ISA Server replacement that requires Server 2008 or Server 2008 R2 doesn’t fucking support IPv6?
IPv6 Support and remote installation
Forefront TMG does not support IPv6.
I mean yes, it supports DirectAccess and thus parts of the IPv6 stack, but that’s it. No IPv6 routing, firewalling, proxying or anything else. You know, IPv6, that silly internet standard that’s been around since 1998 and that is enabled by default in all the supported operating systems for TMG.
