Microsoft Forefront TMG, Long delay when applying Firewall Policy RRS feed

  • Question

  • This is a fresh install of MS Forefront TMG 2010 on a test lab and am experiencing a long delay after enabling or disabling firewall policies.  I have created an allow PING rule from the perimeter network to the local machine.  I can enable this policy and it takes 40 seconds before the client is able to ping successfully.  I disable the policy and it takes a whopping 1 minute and 40 seconds before the client's ability to ping is again blocked.

    We're running this on a PowerEdge with dual athlon 2372s and 16gb memory so I don't see hardware being the issue.  No other performance issues to speak of.  Forefront is on a 2008 R2 server running on top of HyperV.


    Is this delay normal for TMG?
