NIS 5 for Mac and Windows Live Mesh

MacBook Pro running Max OSX 10.7.2.  NIS 5 for Mac.  So here is the problem; when running Windows Live Mesh (ver 15.4.5726.23), Norton Fire Wall constantly pops up multiple alert windows with the following message - "An unknown service port (port XXXXX) is starting on your Mac."  In my situation, the ports started with 31013.  Each alert window advanced the port by one number; so far I am up to 31045.  If I close the Mesh application, the alert windows stop.  Please advise.
