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.

Is this delay normal for TMG?

Since we're using the enterprise version of TMG the system does not update itself immediately.  Rather, it queues the changes and they are applied automatically during the next update cycle.  You can check on the status of your current changes via Monitoring > Configuration tab.
