We made some changes and started port filtering.
The server is now configured to only allow the use of ports: 20, 21, 80,
443, 110 and 125.
After these changes we can no longer use "passive FTP". I'm thinking it's
the random high port assigned by the server based on information I have
found on MS.
The article I found states that the high ports can be configured in the IIS
metabase.xml file. (no info provided as to how) I can't find anything
related to high ports in the metabase file.
Does this sound like it would be causing the problem? How do I go about
configuring the high ports allowed in the meatbase?
Thanks
