Look ‘n’ Stop Application Filtering disadvantages 1) The incapability to backup and re-apply 2) Incapability to specify a port to address. Benefits to specify port to address; - Passive FTP issues - Application: Windows Explorer - - Ports And IP address selection – TCP - Ports: 443 - @ IP: 188.8.131.52 Now if I were to use Internet Explorer with Passive FTP setup, Windows Explorer on XP is seen making TCP initiating connection to FTP server via port 21. Not a problem, add port 21 to the TCP Ports field, now I try to download file off of FTP server, whoops blocking!

Back to modifying for applications “Ports And IP address selection”, add 1024-5000 to the TCP ports list s required. Now what do we have here? Windows Explorer being capable of use to make TCP initiating connections to any remote machine through ports 21, 443, and 1024-5000. And now I’m asking myself what is the point to even bother using “Ports And IP address selection” feature? I’m experiencing these problems with a lot of things I run….
