Microsoft Forefront TMG LONG DELAY when applying Firewall Policy

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?
