Forefront TMG 2010 Turns Two Years Old
Today marks the second anniversary of the release to manufacturing (RTM) for Microsoft Forefront Threat Management Gateway (TMG) 2010. In the two years since its release Microsoft has provided two major service packs that have increased stability, improved performance and scalability, and also added some helpful new functionality. During this time the product also achieved Common Criteria (level EAL4+) certification. As we approach the end of mainstream support for Microsoft ISA Server 2006 SP1, now is a good time to begin evaluating Forefront TMG 2010 and to start planning your migration!
Bug in Forefront TMG 2010 Service Pack 2
Today I confirmed a bug in Service Pack 2 (SP2) for Forefront TMG 2010 that was discovered by Jason Jones. If you have deleted the default Internet Access network rule and replaced it with something else, installing SP2 for Forefront TMG 2010 mysteriously restores this rule. Unfortunately it places the default Internet Access rule ahead of your custom rule which in most cases will cause serious problems. This bug only affects Forefront TMG 2010 configurations where the default Internet Access network rule has been specifically deleted. If you’ve altered this rule in any way, those changes are unaffected.
